On the equivalence between the existence of -kernels and -cokernels
Vitor Gulisz, Wolfgang Rump
We give an elementary proof of the statement that if an idempotent complete preadditive category has weak kernels and weak cokernels, then it has -kernels if and only if it has…
The prime spectrum of an -algebra
W. Rump, L. Vendramin
We prove that the lattice of ideals of an arbitrary -algebra is distributive. As a consequence, a spectral theory applies with no restriction. We also study the spectrum (i.e. t…
Exact categories, big Cohen-Macaulay modules and finite representation type
Chrysostomos Psaroudakis, Wolfgang Rump
One of the first remarkable results in the representation theory of artin algebras, due to Auslander and Ringel-Tachikawa, is the characterization of when an artin algebra is repre…
On the indecomposable involutive set-theoretic solutions of the Yang-Baxter equation of prime-power size
Marco Castelli, Giuseppina Pinto, Wolfgang Rump
We develop a method to construct all the indecomposable involutive set-theoretic solutions of the Yang-Baxter equation with a prime-power number of elements and cyclic permutation…
