Ramified global geometric Langlands correspondence
Ramified global geometric Langlands correspondence
Let , let and be the restricted moduli stacks of local systems on the punctured curve and formal punctured discs, respectively, and let be restriction from the former to the latter. Let be the corresponding relative ind-coherent object. Ramified global geometric Langlands conjecture. Under the conjectural local equivalence
the object corresponds to
This is the spectral description of the Hecke-lisse automorphic object in the ramified setting; it remains conditional on the local equivalence and the restrictedness conjecture.
