$GL_n$的内上同调

Inner cohomology of $GL_n$

Krishna Kishore

摘要:

本文给出了一个附加在一般素数秩线性群$n$上的具有给定水平结构的椭圆局部对称空间的内上同调的一个明确的描述,其系数在复向量空间的局部常数层中。我们表明,对于所有的素数$n$的内部上同调消失在所有程度的非常数层,否则的商模的内部上同调类是不尖的是平凡的素数$n = 2,3$的所有程度,并为所有的素数$n \geq 5$它是平凡的,但它有一个“简单”的描述代数Hecke字符方面的所有程度。

英文摘要:

We give an explicit description of the inner cohomology of an adelic locally symmetric space of a given level structure attached to the general linear group of prime rank $n$, with coefficients in a locally constant sheaf of complex vector spaces. We show that for all prime $n$ the inner cohomology vanishes in all degrees for nonconstant sheaves, otherwise the quotient module of the inner cohomology classes that are not cuspidal is trivial in all degrees for primes $n = 2,3$, and for all primes $n \geq 5$ it is trivial in all but finitely many degrees where it has a `simple' description in terms of algebraic Hecke characters.
