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…
The link surgery modules of 2-component L-space links
Daren Chen, Ian Zemke, Hugo Zhou
In our earlier work, we studied the link surgery modules of two component L-space links. Therein, we computed two of the four idempotents of such modules. In this article, we use K…
Applications of the L-space satellite formula
Daren Chen, Ian Zemke, Hugo Zhou
We give a formula for the -invariant of a satellite knot when is an L-space satellite operator. Our formula holds for general L-space satellite operators when…
L-space satellite operators and knot Floer homology
Daren Chen, Ian Zemke, Hugo Zhou
We consider satellite operators where the corresponding 2-component link is an L-space link. This family includes many commonly studied satellite operators, including cabling opera…
