Zero-surgery characterizes infinitely many knots
Abstract
We prove that 0 is a characterizing slope for infinitely many knots, namely the genus-1 knots whose knot Floer homology is 2-dimensional in the top Alexander grading, which we classified in recent work and which include all (-3,3,2n+1) pretzel knots. This was previously only known for 52 and its mirror, as a corollary of that classification, and for the unknot, trefoils, and the figure eight by work of Gabai from 1987.
