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…

Cohen-Macaulay Type via Lattice Homology and the Motivic Poincaré Series
Alex Hof, András Némethi
We give results on reduced complex-analytic curve germs which relate their indecomposable maximal Cohen-Macaulay (MCM) modules to their lattice homology groups and related invarian…
