Bergman spaces on algebraic curves
László Koltai, Alexander A. Kubasch, Róbert SzÅke
A theorem of Wiegerinck asserts that the Bergman space of an open subset of the complex numbers is either infinite-dimensional or trivial. Recently, this has been generalized to ho…

Lattice cohomology and the embedded topological type of plane curve singularities
Alexander A. Kubasch, GergÅ Schefler
Analytic lattice cohomology is a new invariant of reduced curve singularities. In the case of plane curves, it is an algebro-geometric analogue of Heegaard Floer Link homology. How…

Structural properties of the lattice cohomology of curve singularities
Alexander A. Kubasch, András Némethi, GergŠSchefler
The lattice cohomology of a reduced curve singularity is a bigraded -module , that categorifies the -invariant and…
