Abstract:

To an orthogonal group of signature (n,2), or to a unitary group of any signature, one can attach a Shimura variety. The general problem is to describe the integral models of these Shimura varieties, and their reductions modulo various primes. I will give a conjectural description of supersingular points of the reduction in the orthogonal case, and a complete description of the supersingular points in the case of a unitary group of signature (2,2). This is joint work with G. Pappas.
