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…
