    • Poincaredualitätsalgebren, Koinvarianten und Wu-Klassen 

      Kuhnigk, Kathrin (2003-08-06)
      Certain algebras of coinvariants have the extra structure of a Poincare duality algebra. We describe and characterize some of these Poincare duality algebras via Macaulay inverses of the ...
    • Pointwise conjugate groups and modules over the Steenrod algebra 

      Segal, Joel (2001-11-07)
      The thesis treats pointwise conjugate representations of finite groups and their rings of polynomial invariants, in particular as unstable modules over the Steenrod algebra. Given and n-dimensional linear representation ...
