Title: The equivariant cohomology ring of isotropic quadrics

Abstract:

We compute the bigraded Bredon cohomology ring of isotropic real quadrics with integral Mackey functor coefficients. This complements our previous work on anisotropic quadrics and provides a complete calculation for all real quadrics. These cohomology rings are directly related to the motivic cohomology of the quadrics.
