Abstract: We recall the Betti Geometric Langlands Conjecture proposed by Ben-Zvi-Nadler. In genus 1, we use a uniformization method to calculate the elliptic character sheaves in terms of Lusztig\'s character sheaves, and then construct a functor from the category of elliptic character sheaves (the semistable part of automorphic category) to the spectral category in the Conjecture. The functor is fully-faithful if and only if a certain conjecture of Hecke categories holds. We prove the analogous conjecture for Weyl groups. The construction uses three previous results: Ben-Zvi-Nadler\'s identification of character sheaves as trace of Hecke categories, Bezrukavnikov\'s Langlands duality for affine Hecke categories, and Ben-Zvi-Nadler-Preygel\'s gluing of the spectral categories (in genus 1). This is joint work with D. Nadler.
