Weil's Conjecture for Function Fields

Volume I (AMS-199)

af Dennis Gaitsgory

A central concern of number theory is the study of local-to-global principles, which describe the behavior of a global field K in terms of the behavior of various completions of K. This book looks at a specific example of a local-to-global principle: WeilΓÇÖs conjecture on the Tamagawa number of a semisimple algebraic group G over K. In the case where K is the function field of an algebraic curve X, this conjecture counts the number of G-bundles on X (global information) in terms of the reductio... (Læs mere)
