Whittaker functions from motivic Chern classes
Leonardo C. Mihalcea, Changjian Su, David Anderson
We prove a `motivic' analogue of the Weyl character formula, computing the Euler characteristic of a line bundle on a generalized flag manifold multiplied either by a motivic…
Euler characteristics in the quantum -theory of flag varieties
Anders S. Buch, Sjuvon Chung, Changzheng Li +1
We prove that the sheaf Euler characteristic of the product of a Schubert class and an opposite Schubert class in the quantum -theory ring of a (generalized) flag variety …
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…
