Abstract: I will describe a version of the lattice homology for plane curve singularities using the normalization of their components. These homology can be computed explicitly either from the multi-dimensional semigroup of a singularity or from the multi-variable Alexander polynomial of its link. I will also discuss the relation to Heegaard-Floer homology. The talk is based on the joint work 1301.7636 with Andras Nemethi.
