Hello,

V - vector space

i try to show that if => 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 , with

Do you know this statement?

First of all, i don't understand the definition i(u):=f(u)^t.

if we have ?

edit: it is the interior multiplication

Regards
