Finite groups and $k$-submodular subgroups

Group Theory 2025-05-21 v2

Abstract

For natural numbers nn and kk, the concepts of nn-modularly embedded subgroup, kk-submodular subgroup and kk-LM\mathrm{LM}-group are given, which generalize, respectively, the concepts of modular subgroup, submodular subgroup and LM\mathrm{LM}-group. Classes of groups with given systems of kk-submodular subgroups are investigated.
