DESCRIPTION:Christy Hazel\, University of Oregon\nLet C_2 denote the cycl
 ic group of order two. Given a manifold with a C_2-action\, we can conside
 r its equivariant Bredon RO(C_2)-graded cohomology. In this talk\, we give
  an overview of RO(C_2)-graded cohomology in constant Z/2 coefficients\, a
 nd then explain how a version of the Thom isomorphism theorem in this sett
 ing can be used to develop a theory of fundamental classes for equivariant
  submanifolds. We illustrate how these classes can be used to understand t
 he cohomology of any C_2-surface in constant Z/2 coefficients\, including 
 the ring structure.
