comment “Adjugate” of an endomorphism of a finite-rank free module
Is the "bar" notation standard?

comment “Adjugate” of an endomorphism of a finite-rank free module
Thank you. Do you know by any chance a French term for it? I will wait to see if there will be more answers.

comment Superscript wedge on an $R$-module
Is this a standard notation? I think i have encountered $M^*$ more often.

Well, not really, sort of!

revised “Canonical” symmetrization/skew-symmetrization/alternation of multilinear functions
add an example of a situation where the accepted definition has no reason to be called "canonical"; reorganize

comment “Canonical” symmetrization/skew-symmetrization/alternation of multilinear functions
@KCd: one way in which i consider $v\mapsto(\phi\mapsto\phi(v))$ more natural than, for example, $v\mapsto(\phi\mapsto-\phi(v))$ is that it takes one operation less to define. I will think if i can give a more formal reason to call it "canonical".

comment Signs in the natural map $\Lambda^k V \otimes \Lambda^k V^* \to \Bbbk$
Hm, i didn't understand "every element of $T(V)$ can be written in a unique way" and "For any degree $-1$ derivation $d$ we have $d(v^2)=(dv)v-v(dv)=0$, and so $d$ vanishes on the ideal defining $\bigwedge V$".

comment “Canonical” symmetrization/skew-symmetrization/alternation of multilinear functions
Thanks for the explanations anyway, i will need to think about them. But i am mostly interested in modules over rings.
