Homology cobordism, knot concordance, and Heegaard Floer homology

Jennifer Hom

We review some recent results in knot concordance and homology cobordism. The proofs rely on various forms of Heegaard Floer homology. We also discuss related open problems.

Getting a handle on the Conway knot

Jennifer Hom

A knot is said to be slice if it bounds a smooth disk in the 4-ball. For 50 years, it was unknown whether a certain 11 crossing knot, called the Conway knot, was slice or not, and…

A note on PL-disks and rationally slice knots

Kristen Hendricks, Jennifer Hom, Matthew Stoffregen +1

We give infinitely many examples of manifold-knot pairs (Y, J) such that Y bounds an integer homology ball, J does not bound a non-locally-flat PL-disk in any integer homology ball…

Lectures notes on Heegaard Floer homology

Jennifer Hom

These are the lecture notes for a course on Heegaard Floer homology held at PCMI in Summer 2019. We describe Heegaard diagrams, Heegaard Floer homology, knot Floer homology, and th…

Ribbon knots, cabling, and handle decompositions

Jennifer Hom, Sungkyung Kang, JungHwan Park

The fusion number of a ribbon knot is the minimal number of 1-handles needed to construct a ribbon disk. The strong homotopy fusion number of a ribbon knot is the minimal number of…

Applications of involutive Heegaard Floer homology

Kristen Hendricks, Jennifer Hom, Tye Lidman

We use Heegaard Floer homology to define an invariant of homology cobordism. This invariant is isomorphic to a summand of the reduced Heegaard Floer homology of a rational homology…
