Definition

Suppose $M$ is a differential manifold, $E$ a vector bundle over $M$ , and $\nabla$ a connection over $M$ . Let $p \in M$ and $U ∋ p$ be an open set such that the vector bundle $E$ , restricted to $U$ , is trivial. The curvature matrix of $p$ , denoted $Ω (p)$ is defined by:

$Ω = d ω + ω \land ω$
