Homological Identities for Differential Graded Algebras


ABSTRACT:
  In 1992, Avramov and Foxby asked for a "generalized no-holes theorem" for Bass numbers for local differential graded algebras (DGAs). In this talk I'll descripe a general theory for DGAs which gives an answer to Avramov and Foxby's question and reveals that in the (homological) realm of DGAs you'll find results parallel to the classical Auslander-Buchsbaum formula, and Bass formula. This is joint work with Peter Jørgensen.
