Heegaard Floer homology of some L-space links
by

Coauthors: Andras Nemethi, Jennifer Hom

A link is called an L-space link if all sufficiently large surgeries along it are L-spaces. It is well known that the Heegaard Floer homology of L-space knots have rank 0 or 1 at each Alexander grading. However, for L-space links with many components the homology usually has bigger ranks and a rich structure. I will describe the homology for algebraic and cable links, following joint works with Andras Nemethi and Jen Hom. The key technical tool is a spectral sequence converging to link homology.
