Geometric Representation Theory Seminar

Upcoming talks 06/13 Yang Yang 杨阳 (East China Normal University) Geometric Construction of Quantum affine Schur algebrasThe quantum affine Schur algebras are generalizations of affine Hecke algebras. They naturally appear in quantum Schur-Weyl duality. In this talk, I will firstly provide a geometric construction of a series of generalized quantum affine Schur algebras of any type via equivar...

YMSC Topology Seminar

Enumerative problem for Pell-Abel equation.Andrei B. BOGATYREV, Russian Academy of Sciences (2025-06-10)Abstract:The Pell-Abel (PA) functional equation is the reincarnation of the famous Diophantine equation in the world of polynomials, considered N. H. Abel in 1826. The equation arises in many problems: reduction of Abelian integrals, elliptic billiards, the spectral problem for infinite Jacob...
