Immersed concordance of links and Heegaard Floer homology
Immersed concordance of links and Heegaard Floer homology
An immersed concordance between two links is a concordance with possible self-intersections.Given an immersed concordance we construct a smooth fourdimensional cobordism between surgeries on links.By applying d-invariant inequalities for this cobordism we obtain inequalities between the H-functions of links, which can be extracted from the link Floer homology package.As an …
