A new proof of a theorem concerning decomposable groups
Wojciech Chojnacki
Sažetak
We give an elementary proof of the following result: If G is a compact non-zero Abelian group with dual isomorphic to a subgroup of Q, such that U ∪ (-U) = G \ G(2) and U ∩ (-U) = Ø for some open subset U ⊂ G, where G(2) = {a ∈ G : 2a = 0}, then G is topologically isomorphic with T.
