title = "Tangent cones of numerical semigroup rings",
abstract = "In this paper we describe the structure of the tangent cone of a numerical semigroup ring A = k[[S]] subset of k[[t]] with multiplicity epsilon (as a module over the Noether normalization determined by the fiber cone of the ideal generated by t(e)) in terms of some classical invariants of the corresponding numerical semigroup. Explicit computations are also made by using the GAP system.",
