- A remark on Rasmussen's invariant of knotsPublication . Mackaay, Marco; Turner, Paul; Vaz, PedroWe show that Rasmussen's invariant of knots, which is derived from Lee's variant of Khovanov homology, is equal to an analogous invariant derived from certain other filtered link homologies.
- The 1,2-coloured HOMFLY-PT link homologyPublication . Mackaay, Marco; Stosic, Marko; Vaz, PedroIn this paper we define the 1,2-coloured HOMFLY-PT triply graded link homology and prove that it is a link invariant. We also conjecture on how to generalize our construction for arbitrary colours.
