Hecke algebra action on twisted motivic Chern classes and K-theoretic stable envelopes

Jakub Koncki, Andrzej Weber

Let $G$ be a linear semisimple algebraic group and $B$ its Borel subgroup. Let $T \subset B$ be the maximal torus. We study the inductive construction of Bott-Samelson vari…

Twisted motivic Chern class and stable envelopes

Jakub Koncki, Andrzej Weber

We present a definition of {\em twisted motivic Chern classes} for singular pairs $(X, Δ)$ consisting of a singular space $X$ and a $Q$ -Cartier divisor containing the singul…

Comparison of motivic Chern classes and stable envelopes for cotangent bundles

Jakub Koncki

We consider a complex smooth projective variety equipped with an action of an algebraic torus with a finite number of fixed points. We compare the motivic Chern classes of Białynic…

Motivic Chern classes of configuration spaces

Jakub Koncki

We calculate the equivariant motivic Chern class for configuration space of a quasiprojective (maybe singular) variety and the space of vectors with different directions. We prove…
