Abstract:
I will talk about a q-deformation of (a presentation of) an algebra due to Klyachko, using Macdonald's reduced word identity as motivation. I will focus primarily on a q-analogue of Postnikov's mixed Eulerian numbers that arises naturally in this algebra, and provide probabilistic and combinatorial perspectives on these (re)mixed Eulerian numbers. I will finish by making connections to principal specializations of Schubert polynomials and quasisymmetric polynomials.
