The generating hypothesis in the derived category of a ring
Mark Hovey, Keir Lockridge, Gena Puninski
We show that a strong form (the fully faithful version) of the generating hypothesis, introduced by Freyd in algebraic topology, holds in the derived category of a ring R if and on…

Peter A. Linnell, Gena Puninski, Patrick F. Smith
We prove that every non-finitely generated projective module over the integral group ring of a polycyclic-by-finite group G is free if and only if G is polycyclic.
