The foam and the matrix factorization sl3 link homologies are equivalent
Marco Mackaay, Pedro Vaz
We prove that the foam and matrix factorization universal rational sl3 link homologies are naturally isomorphic as projective functors from the category of link and link cobordisms…

Sl(N) link homology using foams and the Kapustin-Li formula
Marco Mackaay, Marko Stosic, Pedro Vaz
We use foams to give a topological construction of a rational link homology categorifying the slN link invariant, for N>3. To evaluate closed foams we use the Kapustin-Li formula a…
