报告摘要：

In this talk, we extend the notion of virtually Gorenstein rings to the setting of arbitrary rings, and prove that all rings with finite Gorenstein weak global dimension are virtually Gorenstein. Over a virtually Gorenstein ring, we introduce the notion of relative homology functors of complexes with respect to Gorenstein projective (resp., flat) modules, and give a vanishing and a balanced result for this homology. This talk is based on a joint work with Li Liang and Junpeng Wang.
