Almost symmetric good semigroups

Abstract The class of good semigroups is a subsemigroups $${\mathbb {N}}^h$$ N h , that includes the value rings associated to curve singularities and their blowups, allows study combinatorically properties these rings. In this paper we give characterization almost symmetric extending known results in numerical semigroup theory one-dimensional ring theory, apply obtain new on Gorenstein analytically unramified
