The non-centric KK-normalizer conjecture for minimal characteristic bisets

Let F\mathcal F be a saturated fusion system on a finite pp-group SS, let Ω=ΛF\Omega=\Lambda_{\mathcal F} be its minimal characteristic biset, and let PSP\leq S and KAut(P)K\leq\operatorname{Aut}(P) such that KK contains or is contained in Inn(P)\operatorname{Inn}(P). Let N\mathcal N denote the corresponding KK-normalizer fusion system. The non-centric KK-normalizer conjecture. If PP is fully KK-normalized in F\mathcal F, then

NΩK(P)=ΛN,N_{\Omega}^{K}(P)=\Lambda_{\mathcal N},

without requiring PP to be F\mathcal F-centric. The preceding theorem proves the analogous conclusion with an additional centricity hypothesis, while this conjecture asserts that minimal characteristic bisets still model the normalizer fusion system in the non-centric case. The supplied text gives no resolution status.
