nLab Notes on geometric Langlands

This entry is about the collection of notes

on the categorical geometric Langlands conjecture, which is formulated as an equivalence of stable (infinity,1)-categories of


where XX is a smooth complete curve over a field of characteristic zero, and GG is a reductive group and G G^\vee is its Langlands dual. (More precisely, the latter category should be replaced by some appropriate category of ind-coherent sheaves.)
