在局部的、特征为0的、非阿基米德的情况下,我们考虑GL(n+1)上的分布在GL(n)的伴随作用下是不变的。我们证明了这样的分布是不变的换位。这意味着GL(n+1)的容许不可约表示,当限制为GL(n)时,以重数1分解。对于正交群或酉群也得到了类似的定理。
In the local, characteristic 0, non archimedean case, we consider distributions on GL(n+1) which are invariant under the adjoint action of GL(n). We prove that such distributions are invariant by transposition. This implies that an admissible irreducible representation of GL(n+1), when restricted to GL(n) decomposes with multiplicity one. Similar Theorems are obtained for orthogonal or unitary groups.
