Notes on Geometric Langlands
This page will contain a collection of .pdf files intended to share with the community my current understanding of
(global and local, classical and quantum).
Not all papers that appear in the list of references
are ready to be posted, but most of them exist in one form or another, and you're
welcome to request a .pdf file
from me. Otherwise, I'll be posting them gradually.
Needless to say, comments and corrections of any kind are extremely welcome!
Note on the status of the assertions:
If a statement is designated as a "Theorem", this means that the proof exists
(but may have not been written down yet).
If a statement is designated as a "Quasi-Theorem", this means that I see a way how
to prove it, but haven't thought through the details.
If you are a graduate student or
a post-doc interested in the area, you are welcome to supply a proof and claim the result.
