Abstract :
Let be the set of all p-centric subgroups of a finite group G and a prime p. This paper shows that the certain submodule of the Burnside ring Ω(G)(p) of G over the localization of at p has a unique ring structure such that the mark homomorphism φ(p) relative to is an injective homomorphism. A key lemma of this paper is that satisfies the condition (C)p that is discussed by [T. Yoshida, The generalized Burnside ring of a finite group, Hokkaido Math. J. 19 (1990) 509–574]. Díaz and Libman showed that certain ring is isomorphic to the Burnside ring of the fusion system associated to G and a Sylow p-subgroup in [A. Díaz, A. Libman, The Burnside ring of fusion systems, preprint, 2007]. This paper shows that is isomorphic to .
