$Δ$ Invariants of Plumbed Manifolds

Shimal Harichurn, András Némethi, Josef Svoboda

We study the minimal $q$ -exponent $Δ$ in the BPS $q$ -series $Z$ of negative definite plumbed 3-manifolds equipped with a spin $^{c}$ -structure. We express $Δ$ of Seife…

Ordinary $r$ --tuples in cyclic quotient surface singularities

José I. Cogolludo-Agustín, Tamás Lászlo, Jorge Martín-Morales +1

We describe those Weil divisors of cyclic quotient surface singularities which are (abstract) $r$ --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 ${m (c)}_{c \in R}$ in the following context: $(X, o)$ is a complex analytic normal…

Filtrations associated with singularities

András Némethi, Willem Veys

We fix a complex analytic normal singularity germ $(X, o)$ of dimension $\geq 2$ and a (not necessarily irreducible) reduced Weil divisor $(S, o) \subset (X, o)$ . The embedded resoluti…
