Equivariant cohomology of even-dimensional complex quadrics from a combinatorial point of view
5 mars 2024 - 14:00Salle de séminaires IRMARésumé : A 2n-dimensional complex quadric is the manifold defined by a quadratic equation in the (2n+1)-dimensional complex projective space. It has the (n+1)-dimensional torus action which satisfies the GKM conditions. In this talk, I will introduce the equivariant cohomology ring of this space by generators and relations which are described by the subgraphs in the GKM graph. This talk is based on the preprint https://arxiv.org/abs/2305.11332.
