Some split exact sequences in the cohomology of groups
In [Topology 36, No. 4, 783-804 (1997; Zbl 0872.55014); Proc. Symp. Pure Math. 63, 197-220 (1998; Zbl 0891.55021)] \textit{W. G. Dwyer} considered some new spaces which are canonically constructed from the combinatorial structure of the subgroups of a finite group \(G\). In this paper, the authors analyse some split exact sequences of (co)homology groups associated to the spaces of Dwyer.
