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