Let G be a group and G=G_(1)G_(2) where G_(i) are subgroups of G.In this paper,we investigate the structure of G under the conditions that some subgroups of G_(i) are subnormal in G.

A subgroup H of a group G is said to be weakly normal in G if Hg ≤ NG(H) implies that g E NG(H). In this paper, using the condition that the minimal subgroups or subgroups of prime square order of G are weakly no...
