An unoriented skein relation via bordered-sutured Floer homology
David Shea Vela-Vick, C. -M. Michael Wong
We show that the bordered-sutured Floer invariant of the complement of a tangle in an arbitrary 3-manifold , with minimal conditions on the bordered-sutured structure, satisfies…

A note on the knot Floer homology of fibered knots
John A. Baldwin, David Shea Vela-Vick
We prove that the knot Floer homology of a fibered knot is nontrivial in its next-to-top Alexander grading. Immediate applications include new proofs of Krcatovich's result that kn…
