Abstract: We will talk about a conjectured relation between "cofibrant" modules and Gorenstein projective modules for arbitrary groups over any commutative ring of finite global dimension. We will first explain what these classes of modules are and then report on my new work that proves this conjecture for a large class of groups. If time permits, we will then show how the behaviour of these classes of modules with respect to each other has far-reaching applications in generating stable module categories.
