A numerical semigroup S is coated with odd elements (Coe-semigroup), if x − 1, x + 1 ⊆ S for all odd elements x in S. In this note, we will study this kind of numerical semigroup. In particular, we are interested in the study of the Frobenius number, gender and embedding dimension of a numerical semigroup of this type.
Branco et al. (Mon,) studied this question.
