Groups with many subgroups of finite exponent. (English) Zbl 1116.20028
Mostly solvable groups with maximal or minimal condition for subgroups of infinite exponent are considered.
In the case of maximal condition the periodic groups are classified (Theorem 1(c)); in the case of minimal condition the groups are periodic and possess a normal subgroup of finite index and divisible commutator quotient group of finite rank (see Theorem 2).
