报告摘要：In my talk, I will introduce the concept of G-semisimple algebras, which contains several important class of algebras, including gentle algebras. I will begin by discussing the basic properties of G-semisimple algebras. Furthermore, I will explore the subcategory of Gorenstein projective representations Gprj(Q,A) of an acyclic quiver Q over a G-semisimple algebra A, and establish an epivalence between the stable category of Gprj(Q,A) and the category of representations of Q over the stable category Gprj-A. In particular, I will focus on the case where the quiver is of type A_n. I will establish a fascinating periodicity phenomenon in terms of n within the stable Auslander-Reiten quiver of the subcategory of Gorenstein projective representations over A_n.
