The -equivariant ordinary cohomology of complex quadrics III: Exceptional cases

Steven R. Costenoble, Thomas Hudson

In this, the last of three papers about -equivariant complex quadrics, we complete the calculation of the equivariant ordinary cohomology of smooth symmetric quadrics in the c…

The -equivariant ordinary cohomology of complex quadrics I: The antisymmetric case

Steven R. Costenoble, Thomas Hudson

In this, the first of three papers about -equivariant complex quadrics, we calculate the equivariant ordinary cohomology of smooth antisymmetric quadrics. One of these quadric…

The -equivariant ordinary cohomology of

Steven R. Costenoble, Thomas Hudson

We calculate the ordinary -cohomology of with Burnside ring coefficients, using an extended grading that allows us to capture a more natural set of generators. We discu…

A geometric -equivariant Bézout Theorem

Steven R. Costenoble, Thomas Hudson

Classically, Bézout's theorem says that an intersection of hypersurfaces in a projective space is rationally equivalent to a number of copies of a smaller projective space, the num…
