题目：Mod p theta liftings for unitary groups

摘要：Theta liftings are explicit transfers of automorphic forms between two classical groups and play an important role in Langlands program. In this talk, we consider an arithmetic (mod p) version of theta liftings from a compact unitary group to a split unitary group. We construct an explicit theta series which transfers an automorphic form to a non-zero mod p automorphic form under mild conditions. In the end of the talk, we would like to give some applications of the above result.
