Abstract

Let $G$ be a nonabelian group, $A\subset G$ an abelian subgroup and $n\geqslant 2$ an integer.
We say that $G$ has an $n$-abelian partition with respect to $A$,
if there exists a partition of $G$ into  $A$ and $n$ disjoint commuting
subsets $A_1,  A_2,\ldots, A_n$ of $G$,  such that $|A_i|>1$ for each $i=1, 2, \ldots, n$.
We classify all nonabelian groups, up to isomorphism,  which have an $n$-abelian
partition, for $n=2$ and $3$.
