| Jun 24, 2023 at 15:15 | comment | added | darij grinberg | The simplest part of question 1 is finding out which power of the trace of a nilpotent matrix (over an arbitrary commutative ring) is guaranteed to be $0$. See Doron Zeilberger, Gert Almkvist's generalization of a mistake of Bourbaki for the answer to this. Replacing the trace by higher traces should lead to similar answers. See also Exercise 2 in Chapter II of Henri Lombardi, Claude Quitté, Commutative algebra: Constructive methods. Finite projective modules. | |
