A note on a Geography problem in knot Floer homology
arXiv:2010.01205
Abstract
We prove that knot Floer homology of a certain class of knots is non-trivial in next-to-top Alexander grading. This gives a partial affirmative answer to a question posed by Baldwin and Vela-Vick which asks if the same is true for all non-trivial knots in .
The main proof contains a significant error. The author would like to revisit the proof in near future
