Author: jim_stasheff Format: TextThe n-lab is very clear on contraction as a derivation
For example, there is a contraction of a vector $X\in V$ and a $n$-form $\omega\in \Lambda V^*$:
<latex>(X,\omega)\mapsto \iota_X(\omega)</latex>
and $\iota_X: \omega\mapsto \iota_X(\omega)$ is a graded derivation of the exterior algebra of degree $-1$. This is also done for the tangent bundle which is a $C^\infty(M)$-module $V = T M$, then one gets the contraction of vector fields and differential forms. It can also be done in vector spaces, fibrewise.
Is it written somewhere about contraction of a $1$-form $\omega$ with an$n-vector $X\in \in \Lambda V$ as a coderivation?
