On the global dimension three endomorphism algebras of the minimal generator-cogenerator
Edson Ribeiro Alvares, Clezio Aparecido Braga, Sonia Trepode +1
The main goal of this paper is to study the class of algebras for which the global dimension of the endomorphism ring of the generator-cogenerator, given by the sum of the projecti…
