Negative contact surgery on Legendrian non-simple knots
Shunyu Wan, Hugo Zhou
We prove that for any pair of Legendrian representatives of the Chekanov-Eliashberg twist knots with different LOSS invariants, any negative rational contact -surgery with $r\ne…
Cubiquitous Lattices and Branched Covers bounding rational balls
Erica Choi, Nur Saglam, Jonathan Simone +2
Greene and Owens explore cubiquitous lattices as an obstruction to rational homology 3-spheres bounding rational homology 4-balls. The purpose of this article is to better understa…
On homology concordance in contractible manifolds and two bridge links
Hugo Zhou
Let be the group consists of manifold-knot pairs modulo homology concordance, where is an integer homology sphere bounding an integer…
(1,1) almost L-space knots
Fraser Binns, Hugo Zhou
We give a diagrammatic characterization of the knots in the three-sphere and lens spaces which admit large Dehn surgeries to manifolds with Heegaard Floer homology of next-…
PL-genus of surfaces in homology balls
Jennifer Hom, Matthew Stoffregen, Hugo Zhou
We consider manifold-knot pairs where is a homology sphere that bounds a homology ball. We show that the minimum genus of a PL surface in a homology ball such t…
A filtered mapping cone formula for cables of the knot meridian
Hugo Zhou
We construct a filtered mapping cone formula that computes the knot Floer complex of the --cable of the knot meridian in any rational surgery, generalizing Truong's result a…
Homology concordance and an infinite rank free subgroup
Hugo Zhou
Two knots are homology concordant if they are smoothly concordant in a homology cobordism. The group (resp. ) was previou…
