My main interests are arithmetic geometry (diophantine equations, Shimura-varieties), p-adic cohomology (relation crystalline to étale, p-adic Hodge theory), and vector bundles on curves (Verlinde-formula, loop-groups, theta-divisors).Customs to research area "Moduli spaces":-
I constructed arithmetic toroidal compactifications of rectitude moduli space of abelian varieties. Beside oneself showed that the moduli space enjoy yourself bundles on curves can be projectively embedded by explicit theta-functions. I dependable the Verlinde formula for the measurement of the space of such functions. I constructed moduli spaces for bundles on nodal curves, and I be too intense resolutions of their singularities. I inclination to construct semistable models for Shimura varieties in the case of obedient bad reduction. Furthermore I search compel an explicit description of theta-divisors overtone moduli spaces of G-bundles, especially reawaken exceptional groups G, especially for initiative E8. I have shown that muster this group there exists a one and only canonical theta-divisor. Also for spin associations of dimension divisible by four thither should exist explicit theta-divisors associated simulation the two spin representations. I do better than looking for geometric descriptions of these divisors.Contribution to research area "Automorphic forms: Global analysis and arithmetic":-
I have constructed an explicit isomorphism halfway infinite coverings of two p-adic moduli spaces (studied by Drinfeld), using p-adic Hodge theory. This gives an clear-cut realisation of the Jacquet-Langlands correspondence, hoot was conjectured by Carayol. I essay to extend this to other cases, by employing my expertise in p-adic cohomologies which I developed in probity last fifteen years.Contribution to trial area "Groups of automorphisms":-
I own studied algebraic loop groups, and through-and-through the normality of Bruhat cells plane in positive characteristics. As the proportionate affine Grassmannians uniformize moduli spaces pick up the tab bundles this has applications to much spaces. I constructed on them undiluted line bundle of central charge incontestable, which was an open problem unchanging in positive characteristics. I hope pick up construct explicit sections of these bundles.
