A RELATIVE TRACE FORMULA BETWEEN THE GENERAL LINEAR AND THE METAPLECTIC GROUP II: DESCENT
Let F be a number field with ring of adeles A, and let K/F be a quadratic extension. We prove part of a relative trace formula between and corresponding to the descent between and As consequences, we expect a generalization of work of Kohnen and a verification of a conjecture of Furusawa and Martin characterizing -distinction of cuspidal representations of
relative trace formula, descent, symplectic group, metaplectic group.
