Linear periods of automorphic sheaves for GL_{2n}
arXiv:1903.01268 · doi:10.1093/imrn/rnab077
Abstract
We calculate, in the framework of the geometric Langlands program, the periods of cuspidal automorphic sheaves for GL_{2n} along the Levi subgroup GL_n\times\GL_n. We also solve the corresponding local problem.
