$K$-weight bounds for $\gamma$-hyperelliptic semigroups

Abstract

In this note, we show that {\it $\gamma$-hyperelliptic} numerical semigroups of genus $g\gg \gamma$ satisfy a refinement of a well-known characteristic weight inequality due to Torres. The refinement arises from substituting the usual notion of weight by an alternative version, the $K$-weight, which we previously introduced in the course of our study of unibranch curve singularities.
