一般线性群的Shalika模型

Shalika models for general linear groups

Itay Naor

摘要:

定义了$GL_{n+m}(F)$的Shalika模型的推广,并证明了它们是多重性自由的,其中$F$是非阿基米德局部域或有限域,$n,m$是任意自然数.特别地,我们对$n=m$的情形给出了新的证明.我们还证明了$GL_n(F)$的不可约表示与$GL_m(F)$的平凡表示的Bernstein-Zelevinsky积是无重数的.我们通过一个关于Gelfand对的扭曲抛物诱导的猜想将这两个结果联系起来。

英文摘要:

We define a generalization of Shalika models for $GL_{n+m}(F)$ and prove that they are multiplicity-free, where $F$ is either a non-Archimedean local field or a finite field and $n,m$ are any natural numbers. In particular, we give new proof for the case of $n=m$. We also show that the Bernstein-Zelevinsky product of an irreducible representation of $GL_n(F)$ and the trivial representation of $GL_m(F)$ is multiplicity-free. We relate the two results by a conjecture about twisted parabolic induction of Gelfand pairs.
