The motivic Chern classes of the Schubert cells are the K-theoretic generalizations of the Chern-Schwartz-MacPherson classes in homology. I will report some joint work in progress with L. Mihalcea and...

graph hypersurfaces deletion-contraction Algebraic Geometry

Abstract: We study the behavior of the Chern classes of graph hypersurfaces under the operation of deletion-contraction of an edge of the corresponding graph. We obtain an explicit formula when the ed...
We prove explicit formulas for Chern classes of tensor products of vector bundles, with coefficients given by certain universal polynomials in the ranks of the two bundles.
