The tree of good semigroups in and a generalization of the Wilf conjecture
Nicola Maugeri, Giuseppe Zito
In this work, we study good semigroups of introducing the definition of length and genus for these objects. We show how to count the local good semigroup with a fixe…

Embedding dimension of a good semigroup
Nicola Maugeri, Giuseppe Zito
In this paper, we study good semigroups of \mathbb{N}^n, a class of semigroups that contains the value semigroups of algebroid curves with n branches. We give the definition of emb…

An algorithm for computing the Arf closure of an algebroid curve with more than one branch
Nicola Maugeri, Giuseppe Zito
In this paper, we give a fast algorithm for the computation of the Arf closure of an algebroid curve with more than one branch, generalizing an algorithm presented by Arslan and Sa…
