Abstract:
In this paper we describe an algorithm for producing infinitely many examples of set-theoretic complete intersection monomial curves in $\mathbb {P}^{n+1}$, starting with a single set-theoretic complete intersection monomial curve in $\mathbb {P}^{n}$. Moreover we investigate the numerical criteria to decide when these monomial curves can or cannot be obtained via semigroup gluing.References
