Heegaard Floer knot trace invariants, exotic 4-manifolds, and symplectic obstructions

Jennifer Hom, Shunyu Wan

We show that the numerical invariants and coming from knot Floer homology are knot -trace invariants for any integer , resolving the remaining case in Hay…

Ribbon concordance and cabling

Jennifer Hom, JungHwan Park

We study ribbon concordances to cable knots. We formulate a conjecture predicting that any nontrivial knot admitting a ribbon concordance to a (p,q)-cable must itself be a (p,q)-ca…

Distinguishing exotic 's with Heegaard Floer homology

Sean Eli, Jennifer Hom, Tye Lidman

Attaching a Casson handle to a slice disk complement yields a smooth 4-manifold that is homeomorphic to . We show that if two slice knots have sufficiently different…

Naturality and functoriality in involutive Heegaard Floer homology

Kristen Hendricks, Jennifer Hom, Matthew Stoffregen +1

We prove first-order naturality of involutive Heegaard Floer homology, and furthermore construct well-defined maps on involutive Heegaard Floer homology associated to cobordisms be…

Surgery exact triangles in involutive Heegaard Floer homology

Kristen Hendricks, Jennifer Hom, Matthew Stoffregen +1

We establish a surgery exact triangle for involutive Heegaard Floer homology by using a doubling model of the involution. We use this exact triangle to give an involutive version o…

An involutive dual knot surgery formula

Kristen Hendricks, Jennifer Hom, Matthew Stoffregen +1

We prove an involutive analog of the dual knot surgery formula of Eftekhary and Hedden-Levine. We also compute a small model for the local equivalence class of the involutive dual…
