报告摘要:The theory of morphisms being determined by objects was originally investigated by Auslander, and can be seen as the culmination part of Auslander-Reiten theory. This theory provides a more general frame for working with the Auslander-Reiten theory. In this talk, we will discuss the behavior of morphisms determined by objects under G-covering in the sense of Asashiba, which is a generalization of Gabriel's Galois covering functors. As an application, we reformulate Bautista and Liu's framework that G-coverings preserve the sink (or source) morphisms.
