Abstract

Let LL be a commutative Moufang loop (CML) with multiplication group M\frak M, and let F(L)\frak F(L), F(M)\frak F(\frak M) be the Frattini subgroup and Frattini subgroup of LL and M\frak M respectively. It is proved that F(L)=L\frak F(L) = L if and only if F(M)=M\frak F(\frak M) = \frak M and is described the structure of this CLM. Constructively it is defined the notion of normalizer for subloops in CML. Using this it is proved that if F(L)L\frak F(L) \neq L then LL satisfies the normalizer condition and that any divisible subgroup of M\frak M is an abelian group and serves as a direct factor for M\frak M.
