For a saturated fusion system F on a finite p-group S, two different kinds of Burnside rings Ae(F) and A(F) of F have been constructed. The former was introduced by Diaz and Libman in terms of F-centric subgroups of S, and the latter by Reeh in terms of F-stable S-sets.
In this thesis, we construct the F-centric Witt-Burnside ring fWF(Z) of a realized saturated fusion system F over Z and the F-stable Witt-Burnside ring WF(Z) of a saturated fusion system F over Z, which are corresponding to Ae(F) and A(F), respectively. In particular, when F is realized to FS(G) for some finite group G with a Sylow p-subgroup S, we demonstrate the relationship between our Witt-Burnside
rings of F over Z and the classical Witt-Burnside ring of G over Z due to Dress and Siebeneicher.
