Abstract:
Let π be some set of primes. A periodic group G is called a π-group if all prime divisors of the order of each of its elements lie in π. An action of G on a nontrivial group V is called free if, for any v∈V and g∈G such that vg=v, either v=1 or g=1. We describe {2,3}-groups that can act freely on an abelian group.
Keywords:
periodic group, abelian group, free action, local finiteness.
