AI总结:

本文证明了在阿基米德情况下,通用旋群和通用Pin群的不可约Casselman-Wallach表示在限制到子群时具有乘法自由性。

摘要:

设$\GSpin(V)$(resp. $\GPin(V)$)为一个非退化二次空间$V$ over 一个阿基米德局部域$F$的通用旋群(resp. 通用Pin群)。对于一个非退化二次空间$W$ of 维度$n-1$ over $F$,我们还考虑$\GSpin(W)$和$\GPin(W)$。我们证明了在阿基米德情况下,对于一组群($\GSpin(V), \GSpin(W)$)和一组群($\GPin(V), \GPin(W)$)的乘法至多一次定理;即我们证明了将$\GSpin(V)$(resp. $\GPin(V)$)的不可约Casselman-Wallach表示限制到$\GSpin(W)$(resp. $\GPin(W)$)时是乘法自由的。

英文摘要:

Let $\GSpin(V)$ (resp. $\GPin(V)$) be a general spin group (resp. a general Pin group) associated with a nondegenerate quadratic space $V$ of dimension $n$ over an Archimedean local field $F$. For a nondegenerate quadratic space $W$ of dimension $n-1$ over $F$, we also consider $\GSpin(W)$ and $\GPin(W)$. We prove the multiplicity-at-most-one theorem in the Archimedean case for a pair of groups ($\GSpin(V), \GSpin(W)$) and also for a pair of groups ($\GPin(V), \GPin(W)$); namely, we prove that the restriction to $\GSpin(W)$ (resp. $\GPin(W)$) of an irreducible Casselman-Wallach representation of $\GSpin(V)$ (resp. $\GPin(V)$) is multiplicity free.
