Motivic Chern classes of Schubert cells, Hecke algebras, and applications to Casselman's problem
Paolo Aluffi, Leonardo C. Mihalcea, Jörg Schürmann +1
Motivic Chern classes are elements in the K-theory of an algebraic variety , depending on an extra parameter . They are determined by functoriality and a normalization proper…
Positivity of Segre-MacPherson classes
Paolo Aluffi, Leonardo C. Mihalcea, Jörg Schürmann +1
Let be a complex nonsingular variety with globally generated tangent bundle. We prove that the signed Segre-MacPherson (SM) class of a constructible function on with effect…
Pfaffian integrals and invariants of singular varieties
Paolo Aluffi, Mark Goresky
Integrals of the Pfaffian form over the nonsingular part of a projective variety compute information closely related to the Mather-Chern class of the variety and to other invariant…
