The next-to-top term of the knot Floer homology of some non-fibered knots

Fraser Binns, Shunyu Wan

Sivek conjectured that the rank of knot Floer homology in the next-to-top Alexander grading is at least the rank in the top Alexander grading. Baldwin and Vela-Vick verified this c…

Real sutured Heegaard Floer homology

Fraser Binns, Gary Guth, Yonghan Xiao

The paper introduces a theory of real sutured manifolds and defines a real Heegaard Floer homology invariant for them, showing it can be computed combinatorially and has structural…

On Heegaard Floer minimal knots in sutured manifolds

Fraser Binns

Li-Xie-Zhang classified instanton Floer minimal knots in balanced sutured manifolds subject to a condition on the fundamental group. In this paper, we give a similar classification…

(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-…

Closures of -braids and detection

Fraser Binns

We give some new link detection results for link Floer homology, Khovanov homology and annular Khovanov homology. The links we detect arise via different closure operations on -…

Degree-1 maps and rank inequalities in Heegaard Floer homology

Fraser Binns, Sudipta Ghosh

Ghosh-Sivek-Zentner constructed degree-1 maps from certain rational homology solid tori to the twisted -bundle over the Klein bottle. We show that these maps yield rank inequali…
