Numerical Semigroups that Differ from a Symmetric Numerical Semigroup in One Element
- J. C. Rosales
Algebra Colloquium01 Mar 2008
Preview Abstract
Given two numerical semigroups S and S', the distance between S and S' is the cardinality of S\S' plus the cardinality of S'\S. In this paper we study those numerical semigroups S for which there is a symmetric numerical semigroup whose distance to S is one.
