We also prove that if a numerical semigroup can be expressed as an expansion of a numerical semigroup generated by an interval, then it is irreducible and has Toms decomposition.}, title = {Irreducible numerical semigroups having Toms decomposition}, doi = {10.1080/00927870601052505}, author = {Moreno Frías, María Ángeles and Nicola, J. and Pardo Espino, Enrique}, }
