%0 Journal Article %T The set of numerical semigroups of a given genus %A V. Blanco %A J. C. Rosales %J Mathematics %D 2011 %I arXiv %X In this paper we present a new approach to construct the set of numerical semigroups with a fixed genus. Our methodology is based on the construction of the set of numerical semigroups with fixed Frobenius number and genus. An equivalence relation is given over this set and a tree structure is defined for each equivalence class. We also provide a more efficient algorithm based in the translation of a numerical semigroup to its so-called Kunz-coordinates vector. %U http://arxiv.org/abs/1106.1527v1
