The Igusa-Todorov $\phi$-dimension on Morita context algebras

Representation Theory 2022-11-15 v1

Abstract

In this article we prove that, under certain hypotheses, Morita context algebras that have zero bimodule morphisms have finite ϕ\phi-dimension. We also study the behaviour of the ϕ\phi-dimension for an algebra and its opposite. In particular we show that the ϕ\phi-dimension of an Artin algebra is not symmetric, i.e. there exists a finite dimensional algebra AA such that ϕdim(A)ϕdim(Aop)\phi\dim (A) \not = \phi\dim (A^{op}).
