==Definition==
If ''M'' is a manifold and ''P'' is a connection on ''M'', that is a vector-valued 1-form on ''M'' which is a projection on T''M'' such that ''P<sub>a</sub><sup>b</sup>P<sub>b</sub><sup>c</sup>'' = ''P<sub>a</sub><sup>c</sup>'', then the cocurvature <math>\bar{R}_P</math> is a vector-valued 2-form on ''M'' defined by
 
:<math>\bar{R}_P(X,Y) = (\operatorname{Id} - P)[PX,PY]</math>
 
where ''X'' and ''Y'' are vector fields on ''M''.

Jayson Berryhill is how I'm called and my wife doesn't like it at all. For many years he's been living in Alaska and he doesn't plan on altering it. Credit authorising is exactly where my main income arrives from. To perform lacross is the thing I adore most of all.
