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…
Ordinary --tuples in cyclic quotient surface singularities
José I. Cogolludo-AgustÃn, Tamás Lászlo, Jorge MartÃn-Morales +1
We describe those Weil divisors of cyclic quotient surface singularities which are (abstract) --tuple curve singularities.
Multiplier ideals of normal surface singularities
László Koltai, Tamás László, András Némethi
We study the multiplier ideals and the corresponding jumping numbers and multiplicities in the following context: is a complex analytic normal…
Filtrations associated with singularities
András Némethi, Willem Veys
We fix a complex analytic normal singularity germ of dimension and a (not necessarily irreducible) reduced Weil divisor . The embedded resoluti…
