### О примарно факторизуемых группах

Укр. мат. журн. - 1962. - 14, № 1. - С. 3-9

In the present paper the author solves the question of the structure of groups with complemented $p$-subgroups (a subgroup $\mathfrak{U}$ of a group $\mathfrak{G}$ is said to be complemented in $\mathfrak{G}$ if there exists in $\mathfrak{G}$ such a subgroup $\mathfrak{B}$ that $\mathfrak{UB} = \mathfrak{G}$ and $\mathfrak{U} \bigcap \mathfrak{B} = 1$ which was suggested to the author by S. N. Chernikov. If the group is periodical, the necessary and sufficient conditions are given for the p-subgroups of the group to be complemented in it. It is also shown that in general not every subgroup of a periodical group is complemented if all its $p$-subgroups are complemented.
