A simple trace formula. (English) Zbl 0666.10018
A trace formula for automorphic forms of reductive groups is proved for test functions with a single supercuspidal component and another component which is spherical and sufficiently admissible. The resulting formula is used to prove the correspondence of cuspidal modules of $$\mathrm{GL}(n)$$ and metaplectic group.
