From motivic Chern classes of Schubert cells to their Hirzebruch and CSM classes
Paolo Aluffi, Leonardo C. Mihalcea, Jörg Schürmann +1
The equivariant motivic Chern class of a Schubert cell in a `complete' flag manifold is an element in the equivariant K theory ring of to which one adjoins a formal par…
Quantum K theory of Grassmannians, Wilson line operators, and Schur bundles
Wei Gu, Leonardo C. Mihalcea, Eric Sharpe +1
We prove a `Whitney' presentation, and a `Coulomb branch' presentation, for the torus equivariant quantum K theory of the Grassmann manifold , inspired from physi…
Positivity of minuscule quantum K-theory
Anders S. Buch, Pierre-Emmanuel Chaput, Leonardo C. Mihalcea +1
We prove that the Schubert structure constants of the quantum -theory ring of any minuscule flag variety or quadric hypersurface have signs that alternate with codimension. We a…
Hook formulae from Segre-MacPherson classes
Leonardo C. Mihalcea, Hiroshi Naruse, Changjian Su
Nakada's colored hook formula is a vast generalization of many important formulae in combinatorics, such as the classical hook length formula and the Peterson's formula for the num…
