Groups with the real chain condition on non-pronormal subgroups
arXiv:2307.09003
Abstract
It is shown that a gerenalised radical group has no chain of non-pronormal subgroups with the same order type as the set of the real numbers if and only if either the group is minimax or all subgroups are pronormal.
