Acyclic complexes and finitistic dimensions
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.

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.
