Abstract: Let be a reductive -adic group, a good maximal compact subgroup, any open subgroup, and an admissible representation of of finite type. In *A submersion principle and its applications*, Harish-Chandra proves the theorem that is a finite-rank operator for in the regular set in order to show that the character is a locally constant class function on . From this, the authors derive the formula for any -finite matrix coefficient of a discrete series representation with formal degree . They use another technical result of the paper to prove that invariant integrals of Schwartz space functions converge absolutely. None of these results depends upon a characteristic zero assumption.
