Abstract:
Fusion systems are a generalization of the conjugation action
of a finite group on one of its Sylow $p$-subgroups. We define the
fusion system on a pro-$p$-group, and give the saturation axioms in this
context. We show that classical theorems as Alperin fusion theorem
also hold for saturated fusion systems on pro-$p$-groups. In particular,
one can show that morphisms in a saturated fusion system on an uniform
pro-$p$-group can be written as a composition of restrictions of a
finite number of automorphisms. This is a joint work with Peter Symonds.
