In this talk, I will introduce a new homological invariant namely quasi-projective dimension which is a generalization of projective dimension. I will discuss properties of modules with finite quasi-projective dimension and compare it with other homological invariants such as complete intersection dimension and Gorenstein dimension. It turns out that in several cases modules with finite quasi-projective dimension behave similarly to modules of finite complete intersection dimension. Finally, I will address some questions and open problems about this homological invariant.
This talk is based on a joint work with Dave Jorgensen and Ryo Taka ...
