Abstract
In joint work with Shamil Shakirov, we introduced a genus two analogue of Macdonald polynomials. These polynomials form a system of common eigenfunctions for a family of q-difference operators that generalize the A_1-type Macdonald operators. We demonstrated that the algebra generated by these operators together with multiplication operators admits an action of the genus two mapping class group by automorphisms. This generalizes the well-known action of SL(2, Z) on the spherical Double Affine Hecke Algebra.
In this talk, I will present follow-up work in which we derive Cauchy identities for a specialization of our polynomials—specifically, for the genus two Schur polynomials (the t=q=1 case). This work is based on arXiv:2506.18338, joint with Sh. Shakirov and W. Yan.

Speaker Intro
I studied Applied Mathematics and Physics at the Moscow Institute of Physics and Technology, where I earned both my B.Sc. and M.Sc. degrees. In 2013, I joined the graduate program in Mathematics at Rutgers, The State University of New Jersey, and completed my Ph.D. in 2018 under the guidance of Prof. V. Retakh. After earning my doctorate, I held postdoctoral positions at the University of California Berkeley, the Centre de Recherches Mathématiques in Montreal, and the University of Toronto. In July 2024, I became an Associate Professor at the Beijing Institute of Mathematical Sciences and Applications (BIMSA)
