Abstract:The goals of this paper are twofold. One is to look at the behavior of the collections of permutable subgroups and S-permutable subgroups under the intersection map into a fixed subgroup of a group. The other is to locally analyze the intersection map in connection with $${\mathcal{T}}$$ -, $${\mathcal{PT}}$$ -, and $${\mathcal{PST}}$$ -groups. In particular, we generalize Theorem 1 of Bauman Arch. Math. (Basel) 25:337–340, 1974] to $${\mathcal{PT}}$$ - and $${\mathcal{PST}}$$ -groups.
Keywords:T-Groups  Subnormal  Intersection map  Finite groups  Permutable
