摘要:

设F是任意的局部域。考虑GL(n,F)到GL(n+1,F)的标准嵌入和GL(n,F)\times GL(n,F)在GL(n+1,F)上的双边作用。本文证明了GL(n+1,F)上的任何GL(n,F)\times GL(n,F)-不变分布关于转置不变.我们证明了这意味着对(GL(n+1,F),GL(n,F))是Gelfand对.即对(GL(n+1,F))的任意不可约容许表示$(π,E)$,$$dimHom_{GL(n,F)}(E,\cc) \leq 1.$$对于阿基米德情形的证明,我们发展了几种新的工具来研究光滑流形上的不变分布.

英文摘要:

Let F be an arbitrary local field. Consider the standard embedding of GL(n,F) into GL(n+1,F) and the two-sided action of GL(n,F) \times GL(n,F) on GL(n+1,F). In this paper we show that any GL(n,F) \times GL(n,F)-invariant distribution on GL(n+1,F) is invariant with respect to transposition. We show that this implies that the pair (GL(n+1,F),GL(n,F)) is a Gelfand pair. Namely, for any irreducible admissible representation $(π,E)$ of (GL(n+1,F), $$dimHom_{GL(n,F)}(E,\cc) \leq 1.$$ For the proof in the archimedean case we develop several new tools to study invariant distributions on smooth manifolds.
