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…
Arf good semigroups with fixed genus
Giuseppe Zito
In this paper we give an algorithm for the computation of all the Arf numerical semigroups with a given genus. Moreover, we generalize the concept of genus of a numerical semigroup…
Arf good semigroups with fixed conductor
Giuseppe Zito
In this paper we present a new algorithm to calculate the set of Arf numerical semigroups with given conductor. Moreover, we extend the previous problem to the class of good semigr…
On the containment problem for fat points
Iman Bahmani Jafarloo, Giuseppe Zito
Given an ideal , the containment problem is concerned about finding the values and such that the -th symbolic power of is contained in its -th ordinary power.…
