On the projective dimensions of Mackey functors
S. Bouc, R. Stancu, P. J. Webb
We examine the projective dimensions of Mackey functors and cohomological Mackey functors. We show over a field of characteristic that cohomological Mackey functors are Gorenst…
Vanishing evaluations of simple functors
Serge Bouc, Radu Stancu, Jacques Thévenaz
The classification of simple biset functors is known, but the evaluation of a simple biset functor at a finite group G may be zero. We investigate various situations where this hap…
Fusion Systems for Profinite Groups
Radu Stancu, Peter Symonds
We introduce the notion of a pro-fusion system on a pro-p group, which generalizes the notion of a fusion system on a finite p-group. We also prove a version of Alperin's Fusion Th…
Simple biset functors and double Burnside rings
Serge Bouc, Radu Stancu, Jacques Thévenaz
Let G be a finite group and let k be a field. Our purpose is to investigate the simple modules for the double Burnside ring kB(G,G). It turns out that they are evaluations at G of…
On the composition product of saturated fusion systems
Sejong Park, Kári Ragnarsson, Radu Stancu
We say that a fusion system is the composition product of two subsystems if every morphism can be factored as a morphism in one fusion system followed by a morphism in the other. W…
The extension algebra of some cohomological Mackey functors
Serge Bouc, Radu Stancu
Let be a field of characteristic . We construct a new inflation functor for cohomological Mackey functors for finite groups over . Using this inflation functor, we give a…
