Intrinsic Khovanov homology in $RP^{3}$

Qiuyu Ren, Hongjian Yang

We prove that Khovanov homology is an invariant of links in unparametrized $RP^{3}$ 's, i.e., oriented $3$ -manifolds diffeomorphic to $RP^{3}$ . Along the way, we estab…

Adjunction inequality for spatially refined $s$ -invariants

Qiuyu Ren

We note an adjunction inequality in $k CP^{2}$ for the $s$ -version of the $S q^{1}$ -refinement of Rasmussen's $s$ -invariant. This does not hold for general spatial re…

Cosmetic surgery on satellite knots

Qiuyu Ren

We show that if there exists a knot in $S^{3}$ that admits purely cosmetic surgeries, then there exists a hyperbolic one with this property.
