Groups with strongly p-embedded subgroups and cyclic Sylow p-subgroups


We establish necessary conditions under which is contained in a unique maximal subgroup H for a cyclic Sylow p-subgroup P of a quasisimple group G. We then use these results to establish necessary and in most cases sufficient conditions for the special case in which H is a p-local subgroup. Groups satisfying these hypotheses (including the p-local hypothesis) are precisely the groups possessing unfaithful minimal Heilbronn characters, and are relevant to the study of Artin's conjecture on the holomorphy of L-series. Moreover, since in this case is necessarily strongly p-embedded in G, this work complements existing results pertaining to strongly p-embedded subgroups of groups with noncyclic Sylow p-subgroups.
