Positive specializations of symmetric Grothendieck polynomials

Combinatorics 2020-02-24 v2

Abstract

It is a classical fundamental result that Schur-positive specializations of the ring of symmetric functions are characterized via totally positive functions whose parametrization describes the Edrei-Thoma theorem. In this paper we study positive specializations of symmetric Grothendieck polynomials, KK-theoretic deformations of Schur polynomials.
