In the [[mathematics|mathematical]] field of [[representation theory]], a '''weight''' of an [[algebra over a field|algebra]] ''A'' over a field '''F''' is an [[algebra homomorphism]] from ''A'' to '''F''' – a [[linear functional]] – or equivalently, a one dimensional [[Representation (mathematics)|representation]] of ''A'' over '''F'''. It is the algebra analogue of a [[multiplicative character]] of a [[group (mathematics)|group]]. The importance of the concept, however, stems from its application to [[Lie algebra representation|representations]] of [[Lie algebra]]s and hence also to [[group representation|representations]] of [[Algebraic group|algebraic]] and [[Lie group]]s. In this context, a '''weight of a representation''' is a generalization of the notion of an [[eigenvalue]], and the corresponding [[eigenspace]] is called a '''weight space'''. | |||
'' | ==Motivation and general concept== | ||
===Weights=== | |||
Given a set ''S'' of [[matrix (mathematics)|matrices]], each of which is [[diagonalizable matrix|diagonalizable]], and any two of which [[commuting matrices|commute]], it is always possible to [[simultaneously diagonalize]] all of the elements of ''S''.<ref group="note">The converse is also true – a set of diagonalizable matrices commutes if and only if the set is simultaneously diagonalisable {{harv|Horn|Johnson|1985|pp=51–53}}.</ref><ref group="note">In fact, given a set of commuting matrices over an algebraically closed field, they are [[simultaneously triangularizable]], without needing to assume that they are diagonalizable.</ref> Equivalently, for any set ''S'' of mutually commuting [[semisimple operator|semisimple]] [[linear transformation]]s of a finite-dimensional [[vector space]] ''V'' there exists a basis of ''V'' consisting of ''{{anchor|simultaneous eigenvector}}simultaneous [[eigenvector]]s'' of all elements of ''S''. Each of these common eigenvectors ''v'' ∈ ''V'', defines a [[linear functional]] on the subalgebra ''U'' of End(''V'') generated by the set of endomorphisms ''S''; this functional is defined as the map which associates to each element of ''U'' its eigenvalue on the eigenvector ''v''. This "generalized eigenvalue" is a prototype for the notion of a weight. | |||
The notion is closely related to the idea of a [[multiplicative character]] in [[group theory]], which is a homomorphism ''χ'' from a [[group (mathematics)|group]] ''G'' to the [[multiplicative group]] of a [[field (mathematics)|field]] '''F'''. Thus ''χ'': ''G'' → '''F'''<sup>×</sup> satisfies ''χ''(''e'') = 1 (where ''e'' is the [[identity element]] of ''G'') and | |||
:<math> \chi(gh) = \chi(g)\chi(h)</math> for all ''g'', ''h'' in ''G''. | |||
Indeed, if ''G'' [[group representation|acts]] on a vector space ''V'' over '''F''', each simultaneous eigenspace for every element of ''G'', if such exists, determines a multiplicative character on ''G''; the eigenvalue on this common eigenspace of each element of the group. | |||
The notion of multiplicative character can be extended to any [[algebra over a field|algebra]] ''A'' over '''F''', by replacing ''χ'': ''G'' → '''F'''<sup>×</sup> by a [[linear map]] ''χ'': ''A'' → '''F''' with: | |||
:<math> \chi(ab) = \chi(a)\chi(b)</math> | |||
for all ''a'', ''b'' in ''A''. If an algebra ''A'' [[algebra representation|acts]] on a vector space ''V'' over '''F''' to any simultaneous eigenspace corresponds an [[algebra homomorphism]] from ''A'' to '''F''' assigning to each element of ''A'' its eigenvalue. | |||
If ''A'' is a [[Lie algebra]], then the commutativity of the field and the anticommutativity of the Lie bracket imply that this map vanish on [[commutator]]s : ''χ''([a,b])=0. A '''weight''' on a Lie algebra '''g''' over a field '''F''' is a linear map ''λ'': '''g''' → '''F''' with ''λ''([''x'', ''y''])=0 for all ''x'', ''y'' in '''g'''. Any weight on a Lie algebra '''g''' vanishes on the [[derived algebra]] ['''g''','''g'''] and hence descends to a weight on the [[abelian Lie algebra]] '''g'''/['''g''','''g''']. Thus weights are primarily of interest for abelian Lie algebras, where they reduce to the simple notion of a generalized eigenvalue for space of commuting linear transformations. | |||
If ''G'' is a [[Lie group]] or an [[algebraic group]], then a multiplicative character ''θ'': ''G'' → '''F'''<sup>×</sup> induces a weight ''χ'' = d''θ'': '''g''' → '''F''' on its Lie algebra by differentiation. (For Lie groups, this is differentiation at the identity element of ''G'', and the algebraic group case is an abstraction using the notion of a derivation.) | |||
== | ===Weight space of a representation=== | ||
Let ''V'' be a representation of a Lie algebra '''g''' over a field '''F''' and let ''λ'' be a weight of '''g'''. Then the ''weight space'' of ''V'' with weight ''λ'': '''g''' → '''F''' is the subspace | |||
:<math>V_\lambda:=\{v\in V: \forall \xi\in \mathfrak{g},\quad \xi\cdot v=\lambda(\xi)v\}.</math> | |||
A ''weight of the representation'' ''V'' is a weight ''λ'' such that the corresponding weight space is nonzero. Nonzero elements of the weight space are called ''weight vectors''. | |||
If ''V'' is the direct sum of its weight spaces | |||
:<math>V=\bigoplus_{\lambda\in\mathfrak{g}^*} V_\lambda</math> | |||
then it is called a ''{{visible anchor|weight module}};'' this corresponds to having an [[eigenbasis]] (a basis of eigenvectors), i.e., being a [[diagonalizable matrix]]. | |||
Similarly, we can define a weight space ''V''<sub>''λ''</sub> for any [[representation theory|representation]] of a [[Lie group]] or an [[associative algebra]]. | |||
==Semisimple Lie algebras== | |||
Let '''g''' be a [[Lie algebra]], '''h''' a [[maximal]] [[commutative]] [[Lie subalgebra]] consisting of [[Semisimple Lie algebra|semi-simple]] elements (sometimes called [[Cartan subalgebra]]) and let ''V'' be a finite dimensional representation of '''g'''. If '''g''' is [[semisimple Lie algebra|semisimple]], then ['''g''','''g'''] = '''g''' and so all weights on '''g''' are trivial. However, ''V'' is, by restriction, a representation of '''h''', and it is well known that ''V'' is a weight module for '''h''', i.e., equal to the direct sum of its weight spaces. By an abuse of language, the weights of ''V'' as a representation of '''h''' are often called weights of ''V'' as a representation of '''g'''. | |||
Similar definitions apply to a Lie group ''G'', a maximal commutative [[Lie subgroup]] ''H'' and any representation ''V'' of ''G''. Clearly, if ''λ'' is a weight of the representation ''V'' of ''G'', it is also a weight of ''V'' as a representation of the Lie algebra '''g''' of ''G''. | |||
If ''V'' is the [[Adjoint representation of a Lie algebra|adjoint representation]] of '''g''', its weights are called [[root system|roots]], the weight spaces are called root spaces, and weight vectors are sometimes called root vectors. | |||
We now assume that '''g''' is semisimple, with a chosen Cartan subalgebra '''h''' and corresponding [[root system]]. Let us suppose also that a choice of [[positive root]]s Φ<sup>+</sup> has been fixed. This is equivalent to the choice of a set of [[simple root]]s. | |||
[[ | |||
=== | ===Ordering on the space of weights=== | ||
{ | Let <math>\mathfrak{h}_0^*</math> be the real subspace of '''h'''* (if it is complex) generated by the roots of '''g'''. | ||
There are two concepts how to define an [[Order theory|ordering]] of <math>\mathfrak{h}_0^*</math>. | |||
The first one is | |||
:''μ'' ≤ ''λ'' if and only if ''λ'' − ''μ'' is nonnegative linear combination of [[simple root]]s. | |||
The second concept is given by an element <math>f\in\mathfrak{h}_0</math> and | |||
:''μ'' ≤ ''λ'' if and only if ''μ''(''f'') ≤ ''λ''(''f''). | |||
Usually, ''f'' is chosen so that ''β''(''f'') > 0 for each [[positive root]] ''β''. | |||
=== | ===Integral weight=== | ||
A weight ''λ'' ∈ '''h'''* is ''integral'' (or '''g'''-integral), if <math>\lambda(H_\gamma)\in\Z</math> for each [[coroot]] ''H''<sub>γ</sub> such that γ is a positive root. | |||
[[ | The fundamental weights <math>\omega_1,\ldots,\omega_n</math> are defined by the property that they form a basis of '''h'''* dual to the set of [[simple coroot]]s <math>H_{\alpha_1}, \ldots, H_{\alpha_n}</math>. | ||
Hence ''λ'' is integral if it is an integral combination of the fundamental weights. The set of all '''g'''-integral weights is a [[lattice (mathematics)|lattice]]{{dn|date=May 2012}} in '''h'''* called ''weight lattice'' for '''g''', denoted by ''P''('''g'''). | |||
A weight ''λ'' of the Lie group ''G'' is called integral, if for each <math>t\in\mathfrak{h}</math> such that <math>\exp(t)=1\in G,\,\,\lambda(t)\in 2\pi i \mathbf{Z}</math>. For ''G'' semisimple, the set of all ''G''-integral weights is a sublattice <math>P(G)\subset P(\mathfrak{g})</math>. If ''G'' is [[simply connected]], then ''P''(''G'') = ''P''('''g'''). If ''G'' is not simply connected, then the lattice ''P''(''G'') is smaller than ''P''('''g''') and their [[quotient (group theory)|quotient]] is isomorphic to the [[fundamental group]] of ''G''. | |||
===Dominant weight=== | |||
A weight ''λ'' is ''dominant'' if <math>\lambda(H_\gamma)\geq 0</math> for each [[coroot]] ''H''<sub>γ</sub> such that ''γ'' is a positive root. Equivalently, ''λ'' is dominant, if it is a non-negative linear combination of the [[weight (representation theory)#fundamental weight|fundamental weight]]s. | |||
The [[convex hull]] of the dominant weights is sometimes called the ''fundamental Weyl chamber''. | |||
Sometimes, the term ''dominant weight'' is used to denote a dominant (in the above sense) and [[integral weight]]. | |||
===Highest weight=== | |||
A weight ''λ'' of a representation ''V'' is called ''highest-weight'', if no other weight of ''V'' is larger than ''λ''. Sometimes, it is assumed that a highest weight is a weight, such that all other weights of ''V'' are strictly smaller than ''λ'' in the partial ordering given above. The term ''highest weight'' denotes often the highest weight of a "highest-weight module". | |||
Similarly, we define the ''lowest weight''. | |||
The space of all possible weights is a vector space. Let's fix a [[total ordering]] of this vector space such that a nonnegative [[linear combination]] of positive vectors with at least one nonzero coefficient is another positive vector. | |||
Then, a representation is said to have ''highest weight'' ''λ'' if ''λ'' is a weight and all its other weights are less than ''λ''. | |||
Similarly, it is said to have ''lowest weight'' ''λ'' if ''λ'' is a weight and all its other weights are greater than it. | |||
A weight vector <math>v_\lambda \in V</math> of weight ''λ'' is called a ''highest-weight vector'', or ''vector of highest weight'', if all other weights of ''V'' are smaller than ''λ''. | |||
=== | ===Highest-weight module=== | ||
A representation ''V'' of '''g''' is called ''highest-weight module'' if it is generated by a weight vector ''v'' ∈ ''V'' that is annihilated by the action of all [[positive root]] spaces in '''g'''. | |||
This is something more special than a '''g'''-[[module (mathematics)|module]] with a [[highest weight]]. | |||

In the mathematical field of representation theory, a weight of an algebra A over a field F is an algebra homomorphism from A to F – a linear functional – or equivalently, a one dimensional representation of A over F. It is the algebra analogue of a multiplicative character of a group. The importance of the concept, however, stems from its application to representations of Lie algebras and hence also to representations of algebraic and Lie groups. In this context, a weight of a representation is a generalization of the notion of an eigenvalue, and the corresponding eigenspace is called a weight space.
Motivation and general concept
Weights
Given a set S of matrices, each of which is diagonalizable, and any two of which commute, it is always possible to simultaneously diagonalize all of the elements of S.[note 1][note 2] Equivalently, for any set S of mutually commuting semisimple linear transformations of a finite-dimensional vector space V there exists a basis of V consisting of <simultaneous eigenvector>...</simultaneous eigenvector>simultaneous eigenvectors of all elements of S. Each of these common eigenvectors v ∈ V, defines a linear functional on the subalgebra U of End(V) generated by the set of endomorphisms S; this functional is defined as the map which associates to each element of U its eigenvalue on the eigenvector v. This "generalized eigenvalue" is a prototype for the notion of a weight.
The notion is closely related to the idea of a multiplicative character in group theory, which is a homomorphism χ from a group G to the multiplicative group of a field F. Thus χ: G → F× satisfies χ(e) = 1 (where e is the identity element of G) and
Indeed, if G acts on a vector space V over F, each simultaneous eigenspace for every element of G, if such exists, determines a multiplicative character on G; the eigenvalue on this common eigenspace of each element of the group.
The notion of multiplicative character can be extended to any algebra A over F, by replacing χ: G → F× by a linear map χ: A → F with:
for all a, b in A. If an algebra A acts on a vector space V over F to any simultaneous eigenspace corresponds an algebra homomorphism from A to F assigning to each element of A its eigenvalue.
If A is a Lie algebra, then the commutativity of the field and the anticommutativity of the Lie bracket imply that this map vanish on commutators : χ([a,b])=0. A weight on a Lie algebra g over a field F is a linear map λ: g → F with λ([x, y])=0 for all x, y in g. Any weight on a Lie algebra g vanishes on the derived algebra [g,g] and hence descends to a weight on the abelian Lie algebra g/[g,g]. Thus weights are primarily of interest for abelian Lie algebras, where they reduce to the simple notion of a generalized eigenvalue for space of commuting linear transformations.
If G is a Lie group or an algebraic group, then a multiplicative character θ: G → F× induces a weight χ = dθ: g → F on its Lie algebra by differentiation. (For Lie groups, this is differentiation at the identity element of G, and the algebraic group case is an abstraction using the notion of a derivation.)
Weight space of a representation
Let V be a representation of a Lie algebra g over a field F and let λ be a weight of g. Then the weight space of V with weight λ: g → F is the subspace
A weight of the representation V is a weight λ such that the corresponding weight space is nonzero. Nonzero elements of the weight space are called weight vectors.
If V is the direct sum of its weight spaces
then it is called a Template:Visible anchor; this corresponds to having an eigenbasis (a basis of eigenvectors), i.e., being a diagonalizable matrix.
Similarly, we can define a weight space Vλ for any representation of a Lie group or an associative algebra.
Semisimple Lie algebras
Let g be a Lie algebra, h a maximal commutative Lie subalgebra consisting of semi-simple elements (sometimes called Cartan subalgebra) and let V be a finite dimensional representation of g. If g is semisimple, then [g,g] = g and so all weights on g are trivial. However, V is, by restriction, a representation of h, and it is well known that V is a weight module for h, i.e., equal to the direct sum of its weight spaces. By an abuse of language, the weights of V as a representation of h are often called weights of V as a representation of g.
Similar definitions apply to a Lie group G, a maximal commutative Lie subgroup H and any representation V of G. Clearly, if λ is a weight of the representation V of G, it is also a weight of V as a representation of the Lie algebra g of G.
If V is the adjoint representation of g, its weights are called roots, the weight spaces are called root spaces, and weight vectors are sometimes called root vectors.
We now assume that g is semisimple, with a chosen Cartan subalgebra h and corresponding root system. Let us suppose also that a choice of positive roots Φ+ has been fixed. This is equivalent to the choice of a set of simple roots.
Ordering on the space of weights
Let be the real subspace of h* (if it is complex) generated by the roots of g.
There are two concepts how to define an ordering of .
The first one is
- μ ≤ λ if and only if λ − μ is nonnegative linear combination of simple roots.
The second concept is given by an element and
- μ ≤ λ if and only if μ(f) ≤ λ(f).
Usually, f is chosen so that β(f) > 0 for each positive root β.
Integral weight
A weight λ ∈ h* is integral (or g-integral), if for each coroot Hγ such that γ is a positive root.
The fundamental weights are defined by the property that they form a basis of h* dual to the set of simple coroots .
Hence λ is integral if it is an integral combination of the fundamental weights. The set of all g-integral weights is a latticeTemplate:Dn in h* called weight lattice for g, denoted by P(g).
A weight λ of the Lie group G is called integral, if for each such that . For G semisimple, the set of all G-integral weights is a sublattice . If G is simply connected, then P(G) = P(g). If G is not simply connected, then the lattice P(G) is smaller than P(g) and their quotient is isomorphic to the fundamental group of G.
Dominant weight
A weight λ is dominant if for each coroot Hγ such that γ is a positive root. Equivalently, λ is dominant, if it is a non-negative linear combination of the fundamental weights.
The convex hull of the dominant weights is sometimes called the fundamental Weyl chamber.
Sometimes, the term dominant weight is used to denote a dominant (in the above sense) and integral weight.
Highest weight
A weight λ of a representation V is called highest-weight, if no other weight of V is larger than λ. Sometimes, it is assumed that a highest weight is a weight, such that all other weights of V are strictly smaller than λ in the partial ordering given above. The term highest weight denotes often the highest weight of a "highest-weight module".
Similarly, we define the lowest weight.
The space of all possible weights is a vector space. Let's fix a total ordering of this vector space such that a nonnegative linear combination of positive vectors with at least one nonzero coefficient is another positive vector.
Then, a representation is said to have highest weight λ if λ is a weight and all its other weights are less than λ.
Similarly, it is said to have lowest weight λ if λ is a weight and all its other weights are greater than it.
A weight vector of weight λ is called a highest-weight vector, or vector of highest weight, if all other weights of V are smaller than λ.
Highest-weight module
A representation V of g is called highest-weight module if it is generated by a weight vector v ∈ V that is annihilated by the action of all positive root spaces in g.
This is something more special than a g-module with a highest weight.
Similarly we can define a highest-weight module for representation of a Lie group or an associative algebra.
Verma module
Mining Engineer (Excluding Oil ) Truman from Alma, loves to spend time knotting, largest property developers in singapore developers in singapore and stamp collecting. Recently had a family visit to Urnes Stave Church.
For each weight λ ∈ h*, there exists a unique (up to isomorphism) simple highest-weight g-module with highest weight λ, which is denoted L(λ).
It can be shown that each highest weight module with highest weight λ is a quotient of the Verma module M(λ). This is just a restatement of universality property in the definition of a Verma module.
A highest-weight module is a weight module. The weight spaces in a highest-weight module are always finite dimensional.
