Breaking points in the poset of conjugacy classes of subgroups of a finite group

Marius Tărnăuceanu (2019)

Czechoslovak Mathematical Journal

We determine the finite groups whose poset of conjugacy classes of subgroups has breaking points. This leads to a new characterization of the generalized quaternion $2$ -groups. A generalization of this property is also studied.

Let G be a non-periodic locally solvable group. A characterization is given of the subgroups-D of G for which the map $X \to X \cap D$ , for all $X \leq G$ , defines a lattice-endomorphism.
