Abstract

Over any ring, any bounded above acyclic cochain complex of projectives is null-homotopic. Similarly, any bounded below acyclic cochain complex of injectives is null-homotopic. In this talk we consider dual problems, and relate them to the finitistic dimension conjecture, and many other major open problems in homological algebra.
