TitleIsolated gaps in numerical semigroups
ParticipantsLaura Iglésias, Ana Margarida Neto (Principal Investigator), Manuel Silva
SummaryFollowing the study of shifted numerical semigroups initiated in the previous year, several
questions emerged concerning isolated gaps. In this context, our current objective is to study
isolated gaps in numerical semigroups, with particular emphasis on what we call the density of
isolated gaps, that is, the ratio between the number of isolated gaps and the total number of gaps
of a numerical semigroup, as well as on determining its minimum and maximum possible values. We will
begin by studying these problems in specific families of numerical semigroups and later extend the
analysis to other families.
