Published in 2021 at "Mathematische Zeitschrift"

DOI: 10.1007/s00209-021-02829-0

Abstract: We recast the classical notion of “standard tableaux" in an alcove-geometric setting and extend these classical ideas to all “reduced paths" in our geometry. This broader path-perspective is essential for implementing the higher categorical ideas… read more here.

Published in 2022 at "Mathematische Zeitschrift"

DOI: 10.1007/s00209-021-02957-7

Abstract: This paper proves a “positive” Jantzen sum formula for the Specht modules of the cyclotomic Hecke algebras of type A and uses it to obtain new bounds on decomposition numbers. Quite remarkably, our results are proved… read more here.

Published in 2017 at "Israel Journal of Mathematics"

DOI: 10.1007/s11856-018-1779-9

Abstract: In this paper we prove a quantum generalization of Regev’s theorems (Israel. J. Math. 195 (2013), 31–35) by applying the Schur–Weyl duality between the quantum superalgebra and Iwahori–Hecke algebra. We also present an alternative proof… read more here.

Published in 2017 at "Arnold Mathematical Journal"

DOI: 10.1007/s40598-018-0082-5

Abstract: A method is suggested for obtaining the Plancherel measure for Affine Hecke Algebras as a limit of integral-type formulas for inner products in the polynomial and related modules of Double Affine Hecke Algebras. The analytic… read more here.

Published in 2017 at "Advances in Mathematics"

DOI: 10.1016/j.aim.2017.03.004

Abstract: We prove that cyclotomic Yokonuma–Hecke algebras of type A are cyclotomic quiver Hecke algebras and we give an explicit isomorphism with its inverse, using a similar result of Brundan and Kleshchev on cyclotomic Hecke algebras.… read more here.

Published in 2017 at "Duke Mathematical Journal"

DOI: 10.1215/00127094-3792705

Abstract: We compute the equivariant cohomology ring of the moduli space of framed instantons over the affine plane. It is a Rees algebra associated with the center of cyclotomic degenerate affine Hecke algebras of type A.… read more here.

Published in 2020 at "Georgian Mathematical Journal"

DOI: 10.1515/gmj-2020-2078

Abstract: Abstract In this paper, for a discrete hypergroup K and its subhypergroup H, we initiate the related Hecke * {*} -algebra which is an extension of the classical one, and study its basic properties. Especially,… read more here.
