Abstract

Analytic Langlands correspondence was proposed by Etingof, Frenkel and Kazhdan. On one side of this correspondence there are certain operators on L2(BunG)L^2(\operatorname{Bun}_G), called Hecke operators, where BunG\operatorname{Bun}_G is the variety of stable GG-bundles on XX and L2(BunG)L^2(\operatorname{Bun}_G) is a Hilbert space of square-integrable half-densities. The compactness conjecture says that Hecke operators are bounded and, moreover, compact. In arXiv:2106.05243 Etingof, Frenkel and Kazhdan prove this and other conjectures in the case of G=PGL2G=\operatorname{PGL}_2 and X=P1X=\mathbb{P}^1 with parabolic structures. We investigate the case of G=PGL2G=\operatorname{PGL}_2 and genus one curve over complex numbers with parabolic structures. We obtain an explicit formula for Hecke operators and prove the compactness conjecture in this case.
