So, I got curious about Geometric Langlands. I have heard about the two words, and also used it myself, but I don't know exactly what I am talking about. There are some equivalence of categories, which is a nice way to package my ignorance. There is a hard side, and an easy side. The hard side involves certain constructible sheaves on $Bun_G$ with some singular support in the global Nilpotent cone, the easy side involves some local system on the same curve but valued in the dual Langlands group.
Is the abelian case known?
What is an example of this? Some sample curve, and sample group?
Under some nice cases, the local Hecke eigensheaf in $D^bSh(Bun_G(X))$ is also a global Hecke eigensheaf. How to think about $Bun_G$ and sheaves on it? A point in $Bun_G$ is a $G$-bundle over $X$, but we are not just thinking about
