Abstract
23.1 Let P be a finite p-group and F a Frobenius P-category. As in chapter 4, denote by Fsc the full subcategory of F over the set of F-selfcentralizing subgroups of P and by \( \tilde F^{sc} \) its exterior quotient (cf. 1.3). In this chapter, we exhibit some significant quotients of the full subcategory Lb,sc of Lb over the set of F-selfcentralizing subgroups of P — namely, the polycentral and the reduced Fsc-localities — which are necessary candidates to contain any perfect Fsc-locality, as we show in the last chapter; in particular, we give a sufficient condition for the existence of a perfect Fsc-locality (cf. 17.4 and 17.13). We freely use the notation introduced in the previous chapter and abundantly employ the terminology and the results of chapter 6.
