DESCRIPTION:Marc Stephan (University of British Columbia)\nA basic open pr
 oblem in equivariant topology is to determine lower bounds for the sum of 
 mod-p Betti numbers of finite CW-complexes with a free (Z/p)^n-action. For
  p=2\, Carlsson connected chain complexes with a free (Z/p)^n-action to DG
  modules over a polynomial ring in order to establish lower bounds using c
 ommutative algebra.\n\nIn joint work with Jeremiah Heller\, we extend this
  connection to all primes using p-DG modules as developed in the Hopfologi
 cal algebra framework by Khovanov and Qi. In this talk\, I will provide an
  introduction to Hopfological algebra and explain its relevance for our wo
 rk.
