摘要
If a group G of finite virtual cohomological dimension has p-periodic Farrell cohomology, then the Yagita invariant of this group equals its p-period. The group of symplectic 2(p + 1) x 2(p + 1) matrices over has elementary abelian p-subgroups of rank at least 2 and hence and do not have p-periodic Farrell cohomology. We compute the Yagita invariants of these groups for any odd prime p.
