Abstract

The colloquium will discuss a variant of the multiplicity one theorem for modular forms, and consider the question of when the set of Hecke eigenvalues of a cusp form on GL(n) is contained in the set of Hecke eigenvalues of a cusp form on GL(m) for n≤m. We will also discuss an analogous question about group representations which seems not to have been considered before. Joint work with R. Raghunathan.
