Curvature criterion for vanishing of group cohomology
arXiv:1912.05839
Abstract
We introduce a new geometric criterion for vanishing of cohomology for BN-pair groups. In particular, this new criterion yields a sharp vanishing of cohomology result for all BN-pair groups acting on non-thin affine building.
