On groups with the minimal condition for non-invariant decomposable abelian subgroups

Abstract

The infinite groups, in which there is no any infinite descending chain of non-invariant decomposable abelian subgroups (\(md\)-groups) are studied. Infinite groups with the minimal condition for non-invariant abelian subgroups, infinite groups with the condition of normality for all decomposable abelian subgroups and others belong to the class of \(md\)-groups. The complete description of infinite locally finite and locally soluble non-periodic \(md\)-groups is given, the connection of the class of \(md\)-groups with other classes of groups are investigated.
