Let K be a field of characteristic p > 0 and let G be a direct
sum of cyclic groups, such that its torsion part is a p-group. If there exists
a K-isomorphism KH ∼= KG for some group H, then it is shown that
H ∼= G.
Let G be a direct sum of cyclic groups, a divisible group or a simply
presented torsion abelian group. Then KH ∼= KG as K-algebras for all
fields K and some group H if and only if H ∼= G.
