摘要

摘要我们通过$\ell^2$-同调证明了全局函数域上简单单连通Chevalley群的乘积中的格的有理同调维数等于有理上同调维数和相关的Bruhat–Tits构造的维数。

A note on the rational homological dimension of lattices in positive characteristic

Abstract We show via $\ell^2$ -homology that the rational homological dimension of a lattice in a product of simple simply connected Chevalley groups over global function fields is equal to the rational cohomological dimension and to the dimension of the associated Bruhat–Tits building.
