尖点Theta表示存在的判据

Criteria for the Existence of Cuspidal Theta Representations

Solomon Friedberg, David Ginzburg

摘要:

Theta表示作为群覆盖上的爱森斯坦级数的留数出现在全局上;它们的未分歧的局部成分可以表征为某些主列的从属项。尖点θ表示是几乎在所有地方都等于局部扭曲θ表示的表示。尖点θ表示已知存在,但仅用于$GL_j$,$j\leq 3$的覆盖。本文建立了任意秩的一般线性群的$r$ -折叠亚复盖上尖点θ表示存在的必要条件。

英文摘要:

Theta representations appear globally as the residues of Eisenstein series on covers of groups; their unramified local constituents may be characterized as subquotients of certain principal series. A cuspidal theta representation is one which is equal to the local twisted theta representation at almost all places. Cuspidal theta representations are known to exist but only for covers of $GL_j$, $j\leq 3$. In this paper we establish necessary conditions for the existence of cuspidal theta representations on the $r$-fold metaplectic cover of the general linear group of arbitrary rank.
