报告摘要：
In homological algebra, ring theory, and representation theory of algebras and groups, Morita context rings appear very common. Compared with projective modules over Morita context rings, Gorenstein-projective modules are quite difficult to describe. In this talk, we give necessary and sufficient conditions for Gorenstein-projective modules over a class of Morita context rings by Gorenstein-projective modules over the constitute rings of Morita contexts. The talk presents a part of a joint work with Q. Q. Guo.
