Let G be a finite group and H a subgroup of G. We say that H is an -subgroup of G if NG (H) ∩ HgH for all gG; H is called weakly -embedded in G if G has a normal subgroup K such that HG = HK and HK is an -subgroup of G, where HG is the normal clousre of H in G, i. e., HG = 〈Hg|gG〉. In this paper, we study the p-nilpotence of a group G under the assumption that every subgroup of order d of a Sylow p-subgroup P of G with 1 < d < |P| is weakly -embedded in G. Many known results related to p-nilpotence of a group G are generalized.
