A diagrammatic grading bound for colored link homology
Hongjian Yang
We establish a grading bound for colored link homology that can be read off from any link diagram. In the context of contact geometry, this gives a bound on the T…
Intrinsic Khovanov homology in
Qiuyu Ren, Hongjian Yang
We prove that Khovanov homology is an invariant of links in unparametrized 's, i.e., oriented -manifolds diffeomorphic to . Along the way, we estab…
The flip map and involutions on Khovanov homology
Daren Chen, Hongjian Yang
The flip symmetry on knot diagrams induces an involution on Khovanov homology. We prove that this involution is determined by its behavior on unlinks; in particular, it is the iden…
Instantons and Khovanov homology in
Hongjian Yang
We study the instanton Floer homology for links in and compute the second page of Kronheimer--Mrowka's spectral sequence. As an application, we show that Khovanov h…
A homological action on sutured instanton homology
Hongjian Yang
We define a homological action on sutured instanton Floer homology. This action is well-defined up to scalars, and behaves well under connected sums and sutured manifold decomposit…
