Titre Moduli spaces of bundles and Kloosterman sums
Horaire10:30 à 11:30
RésumeUnlike in the classical theory of modular forms, there are very few explicit examples of modular forms known in the setup of the geometric Langlands correspondence (which we will recall). In joint work with B.C. Ngô and Z. Yun which was motivated by work of Gross and Frenkel - we found an explicit series of such forms which on the one hand give an example of the (wild) geometric Langlands correspondence and on the other hand turn out to be closely related to classical Kloosterman sums.
