the Burnside ring A (G) of finite groups. We show that these rings have several properties in common. When F is the fusion system of G we describe the relationship between these rings.
Given a saturated fusion system F on a finite p-group S we define a ring A(F) modeled on the Burnside ring A(G) of finite groups. We show that these rings have several properties in common. When F is the fusion system of G we describe the relationship between these rings.
