The analytic lattice cohomology of isolated singularities
Tamás Ágoston, András Némethi
We associate (under a minor assumption) to any analytic isolated singularity of dimension the `analytic lattice cohomology' ${\mathbb H}^*_{an}=\oplus_{q\geq 0}{\mathbb H…
Analytic lattice cohomology of surface singularities, II (the equivariant case)
Tamás Ágoston, András Némethi
We construct the equivariant analytic lattice cohomology associated with the analytic type of a complex normal surface singularity whenever the link is a rational homology sphere.…
Analytic lattice cohomology of surface singularities
Tamás Ágoston, András Némethi
We construct the analytic lattice cohomology associated with the analytic type of any complex normal surface singularity. It is the categorification of the geometric genus of the g…
Polar exploration of complex surface germs
André Belotto da Silva, Lorenzo Fantini, András Némethi +1
We prove that the topological type of a normal surface singularity provides finite bounds for the multiplicity and polar multiplicity of , as well as for the combina…
Local Newton nondegenerate Weil divisors in toric varieties
András Némethi, Baldur Sigurðsson
We introduce and develop the theory of Newton nondegenerate local Weil divisors in toric affine varieties. We characterize in terms of the toric combinatorics of the Newton…
Local invariants of minimal generic curves on rational surfaces
José Ignacio Cogolludo-Agustín, Tamás László, Jorge Martín-Morales +1
Let (C,0) be a reduced curve germ in a normal surface singularity (X,0). The main goal is to recover the delta invariant of the abstract curve (C,0) from the topology of the embedd…
