Representability of systems of proportionally modular numerical semigroups
Zsolt Baja, Tamás László, Zsuzsa Nagy
The authors prove that any system of proportionally modular numerical semigroups can be represented by a canonical equivariant resolution of a weighted homogeneous surface singular…

Delta invariant of -Cartier curve germs and the genus of representable numerical semigroups
Zsolt Baja, Tamás László, András Némethi
In this article, first we give two formulae for the delta invariant of a complex curve singularity that can be embedded as a -Cartier divisor in a normal surface singu…

Flat semigroups and weighted homogeneous surface singularities
Zsolt Baja, Tamás László
We consider numerical semigroups associated with normal weighted homogeneous surface singularities with rational homology sphere links. We say that a semigroup is representable if…
