       Unstable cohomology of SL_n(Z) and Hopf algebras
       Peter Patzt (University of Oklahoma)
    • Abstract:
      The cohomology of SL_n(Z) has many connections to geometry and number theory and is largely unknown. In this talk, I will give a survey about what is known about it. In particular, I will include newly found unstable classes which come from a Hopf algebra structure. This talk is on joint work with Avner Ash and Jeremy Miller.
