# Weil bound for characters sums. (reference-request )

Do you know on any good reference on Weil bound for charcter sums over algebraic curves. I prefer reference which assume few previous knowlage.

I did some retagging, mainly because this was already on the front page. The two answers so far are both lecture notes or textbooks, and I suspect you're going to get mostly textbook type answers because you want it to assume little background. – David White Sep 13 '11 at 14:25

Yes, check out this paper:
