# Thread: Anti-derivation

1. ## Anti-derivation

Hello,

V - vector space
i try to show that if $u \in V$ => $i(u) \in End(\Lambda(V))$ is an anti-derivation of
degree -1.

I'm sorry but i'm not sure what this function i(u) is. It could be the interior multiplication???
I have found the following informations: i(u):=f(u)^t and $f(u)(v):=u \wedge v$ , with $f(u) \in \Lambda(V)$
Do you know this statement?
First of all, i don't understand the definition i(u):=f(u)^t.

if we have $i(u \wedge v)=f(u \wedge v)^t=$?

edit: it is the interior multiplication

Regards
