Algebras generated by two quadratic elements
Vesselin Drensky, Jeno Szigeti, Leon van Wyk
Let K be a field of any characteristic and let R be an algebra generated by two elements satisfying quadratic equations. Then R is a homomorphic image of F=K<x,y | x^2+ax+b=0,y^2+c…

Centralizers in endomorphism rings
Vesselin Drensky, Jeno Szigeti, Leon van Wyk
We prove that the centralizer Cen(f) in Hom_R(M,M) of a nilpotent endomorphism f of a finitely generated semisimple left R-module M (over an arbitrary ring R) is the homomorphic im…
