The [[mathematical notation]] of '''multi-indices''' simplifies formulae used in [[multivariable calculus]], [[partial differential equation]]s and the theory of [[distribution (mathematics)|distribution]]s, by generalising the concept of an integer [[index notation|index]] to an ordered [[tuple]]  of indices.
In [[mathematics]], the '''Cesàro means''' (also called '''Cesàro averages''') of a [[sequence]] (''a''<sub>''n''</sub>) are the terms of the sequence (''c''<sub>''n''</sub>), where


==Multi-index notation==
:<math>c_n = \frac{1}{n} \sum_{i=1}^{n} a_i</math>
An ''n''-dimensional '''multi-index''' is an ''n''-[[tuple]]


:<math>\alpha = (\alpha_1, \alpha_2,\ldots,\alpha_n)</math>  
is the [[arithmetic mean]] of the first ''n'' elements of (''a''<sub>''n''</sub>).

of [[natural number|non-negative integers]] (i.e. an element of the ''n''-[[dimension]]al [[set]] of [[natural number]]s, denoted <math>\mathbb{N}^n_0</math>). For multi-indices <math>\alpha, \beta \in \mathbb{N}^n_0</math> and <math>x = (x_1, x_2, \ldots, x_n) \in \mathbb{R}^n</math> one defines:

:<math>\lim_{n \to \infty} c_n = A.</math>


;[[Partial order]]
That is, the operation of taking Cesàro means preserves [[Limit of a sequence|convergent sequence]]s and their limits. This is the basis for taking Cesàro means as a [[summability method]] in the theory of [[divergent series]].
:<math>\alpha \le \beta \quad \Leftrightarrow \quad \alpha_i \le \beta_i \quad \forall\,i\in\{1,\ldots,n\}</math>
If the sequence of the Cesàro means is convergent, the series is said to be ''Cesàro summable''.  There are certainly many examples for which the sequence of Cesàro means converges, but the original sequence does not: for example with


;Sum of components (absolute value)
: <math>a_n=\begin{cases}1&\mbox{if }n=2k-1, \\ 0&\mbox{if }n=2k\end{cases}</math>,
:<math>| \alpha | = \alpha_1 + \alpha_2 + \cdots + \alpha_n</math>


;[[Factorial]]
we have an [[oscillating sequence]], but the means have limit <math>\frac{1}{2}</math>. (See also [[Grandi's series]].)
:<math>\alpha ! = \alpha_1! \cdot \alpha_2! \cdots \alpha_n!</math>


;[[Binomial coefficient]]
Another example is the sequence <math>a_n=(-1)^n</math> which is Cesàro summable to <math>1/2</math> and has Cesàro-mean <math> 0 </math>.
:<math>\binom{\alpha}{\beta} = \binom{\alpha_1}{\beta_1}\binom{\alpha_2}{\beta_2}\cdots\binom{\alpha_n}{\beta_n} = \frac{\alpha!}{\beta!(\alpha-\beta)!}</math>


;[[Multinomial coefficient]]
Cesàro means are often applied to [[Fourier series]],
:<math>\binom{k}{\alpha} = \frac{k!}{\alpha_1! \alpha_2! \cdots \alpha_n! } = \frac{k!}{\alpha!} </math>

since the means (applied to the [[trigonometric polynomial]]s making up the symmetric [[partial sum]]s) are more powerful in summing such series than [[pointwise convergence]]. The kernel that corresponds is the [[Fejér kernel]], replacing the [[Dirichlet kernel]]; it is positive, while the Dirichlet kernel takes both positive and negative values. This accounts for the superior properties of Cesàro means for summing Fourier series, according to the general theory of [[approximate identity|approximate identities]].

==Some applications==
The multi-index notation allows the extension of many formulae from elementary calculus to the corresponding multi-variable case. Below are some examples. In all the following, <math>x,y,h\in\mathbb{C}^n</math> (or <math>\mathbb{R}^n</math>), <math>\alpha,\nu\in\mathbb{N}_0^n</math>, and <math>f,a_\alpha\colon\mathbb{C}^n\to\mathbb{C}</math> (or <math>\mathbb{R}^n\to\mathbb{R}</math>).
 
;[[Multinomial theorem]]
 
:<math> \biggl( \sum_{i=1}^n x_i\biggr)^k = \sum_{|\alpha|=k} \binom{k}{\alpha} \, x^\alpha</math>
 
;[[Multi-binomial theorem]]
 
:<math> (x+y)^\alpha = \sum_{\nu \le \alpha} \binom{\alpha}{\nu} \, x^\nu y^{\alpha - \nu}.</math>
 
;[[Leibniz rule (generalized product rule)|Leibniz formula]]
For smooth functions ''f'' and ''g''
 
:<math>\partial^\alpha(fg) = \sum_{\nu \le \alpha} \binom{\alpha}{\nu} \, \partial^{\nu}f\,\partial^{\alpha-\nu}g.</math>
 
;[[Taylor series]]
For an [[analytic function]] ''f'' in ''n'' variables one has
 
:<math>f(x+h) = \sum_{\alpha\in\mathbb{N}^n_0}^{}{\frac{\partial^{\alpha}f(x)}{\alpha !}h^\alpha}.</math>
In fact, for a smooth enough function, we have the similar '''Taylor expansion'''
:<math>f(x+h) = \sum_{|\alpha| \le n}{\frac{\partial^{\alpha}f(x)}{\alpha !}h^\alpha}+R_{n}(x,h),</math>
where the last term (the remainder) depends on the exact version of Taylor's formula. For instance, for the Cauchy formula (with integral remainder), one gets
:<math>R_n(x,h)= (n+1) \sum_{|\alpha| =n+1}\frac{h^\alpha}{\alpha !}\int_0^1(1-t)^n\partial^\alpha f(x+th)\,dt.</math>
 
;General [[partial differential operator]]
A formal ''N''-th order partial differential operator in ''n'' variables is written as
 
:<math>P(\partial) = \sum_{|\alpha| \le N}{}{a_{\alpha}(x)\partial^{\alpha}}.</math>
 
;[[Integration by parts]]
For smooth functions with [[compact support]] in a bounded domain <math>\Omega \subset \mathbb{R}^n</math> one has
 
:<math>\int_{\Omega}{}{u(\partial^{\alpha}v)}\,dx = (-1)^{|\alpha|}\int_{\Omega}^{}{(\partial^{\alpha}u)v\,dx}.</math>
 
This formula is used for the definition of [[Distribution (mathematics)|distribution]]s and [[weak derivative]]s.
 
==An example theorem==
If <math>\alpha,\beta\in\mathbb{N}^n_0</math> are multi-indices and <math>x=(x_1,\ldots, x_n)</math>, then
 
:<math> \part^\alpha x^\beta =
\begin{cases}
\frac{\beta!}{(\beta-\alpha)!} x^{\beta-\alpha} & \hbox{if}\,\, \alpha\le\beta,\\
0 & \hbox{otherwise.} \end{cases}</math>
 
===Proof===
The proof follows from the [[power rule]] for the [[differential calculus|ordinary derivative]]; if ''&alpha;'' and ''&beta;'' are in {0,&nbsp;1,&nbsp;2,&nbsp;.&nbsp;.&nbsp;.}, then
 
:<math> \frac{d^\alpha}{dx^\alpha} x^\beta = \begin{cases} \frac{\beta!}{(\beta-\alpha)!} x^{\beta-\alpha} & \hbox{if}\,\, \alpha\le\beta, \\ 0 & \hbox{otherwise.} \end{cases}\qquad(1)</math>
 
Suppose <math>\alpha=(\alpha_1,\ldots, \alpha_n)</math>, <math>\beta=(\beta_1,\ldots, \beta_n)</math>, and <math>x=(x_1,\ldots, x_n)</math>. Then we have that
 
:<math>\begin{align}\part^\alpha x^\beta&= \frac{\part^{\vert\alpha\vert}}{\part x_1^{\alpha_1} \cdots \part x_n^{\alpha_n}} x_1^{\beta_1} \cdots x_n^{\beta_n}\\
&= \frac{\part^{\alpha_1}}{\part x_1^{\alpha_1}} x_1^{\beta_1} \cdots
\frac{\part^{\alpha_n}}{\part x_n^{\alpha_n}} x_n^{\beta_n}.\end{align}</math>
 
For each ''i'' in {1,&nbsp;.&nbsp;.&nbsp;.,&nbsp;''n''}, the function <math>x_i^{\beta_i}</math> only depends on <math>x_i</math>. In the above, each partial differentiation <math>\part/\part x_i</math> therefore reduces to the corresponding ordinary differentiation <math>d/dx_i</math>. Hence, from equation (1), it follows that <math>\part^\alpha x^\beta</math> vanishes if ''&alpha;<sub>i</sub>''&nbsp;>&nbsp;''&beta;<sub>i</sub>'' for at least one ''i'' in {1,&nbsp;.&nbsp;.&nbsp;.,&nbsp;''n''}. If this is not the case, i.e., if ''&alpha;''&nbsp;&le;&nbsp;''&beta;'' as multi-indices, then
 
:<math> \frac{d^{\alpha_i}}{dx_i^{\alpha_i}} x_i^{\beta_i} = \frac{\beta_i!}{(\beta_i-\alpha_i)!} x_i^{\beta_i-\alpha_i}</math>
for each <math>i</math> and the theorem follows. <math>\Box</math>

That is, the operation of taking Cesàro means preserves convergent sequences and their limits. This is the basis for taking Cesàro means as a summability method in the theory of divergent series. If the sequence of the Cesàro means is convergent, the series is said to be Cesàro summable. There are certainly many examples for which the sequence of Cesàro means converges, but the original sequence does not: for example with

an={1if n=2k−1,0if n=2k,

we have an oscillating sequence, but the means have limit 12. (See also Grandi's series.)

Another example is the sequence an=(−1)n which is Cesàro summable to 1/2 and has Cesàro-mean 0.

Cesàro means are often applied to Fourier series, [2]Primarily based on the most recent URA personal property value index (PPPI) flash estimates, we know that the PPPI, which represents the overall real property price development, has dipped in 2013Q4.
