Nilpotent elements in Grothendieck rings

open access: yesIllinois Journal of Mathematics, 1988
Let \(M_ 1,...,M_ n\) be isomorphism classes of finitely presented modules over a commutative ring R. One forms the ring \({\mathbb{Z}}[M_ 1,...,M_ n]\) with \(\oplus\) and \(\otimes\) as addition and multiplication, and with the obvious relations. It is shown that if M and N are locally isomorphic, then there is an integer n, depending on M, N and R ...

Nilpotent matrices over antirings [PDF]

open access: yes, 2018
The main goal of this thesis is to decribe the properties of nilpotent matrices over antirings. We start with the introduction of the abstract structures, more precisely, groups and semirings.

Hermitian Characteristics of Nilpotent Elements

open access: yes, 2002
We define and study several equivariant stratifications of the isotropy and coisotropy representations of a parabolic subgroup in a complex reductive group.

On the representation of an idempotent as a sum of nilpotent elements

open access: yes, 1995
In this paper we study in which rings a non-zero idempotent element can be presented as a sum of two nilpotent ...

The number of nilpotent semigroups of degree 3

open access: yes, 2012
A semigroup is \emph{nilpotent} of degree 3 if it has a zero, every product of 3 elements equals the zero, and some product of 2 elements is non-zero.

NILPOTENT ELEMENTS IN THE JACOBSON-WITT ALGEBRA OVER A FINITE FIELD

open access: yes, 2020
It is shown in this paper that the number of nilpotent elements in the Jacobson-Witt algebra W n over a finite field Fq is equal to the expected power of q.
