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

Combinatorics 2019-06-19 v2 Algebraic Geometry

Abstract

In this note, we show that {\it γ\gamma-hyperelliptic} numerical semigroups of genus gγg \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 KK-weight, which we previously introduced in the course of our study of unibranch curve singularities.
