Functoriality of colored link homologies

Michael Ehrig, Daniel Tubbenhauer, Paul Wedrich

We prove that the bigraded colored Khovanov-Rozansky type A link and tangle invariants are functorial with respect to link and tangle cobordisms.

Singular TQFTs, foams and type D arc algebras

Michael Ehrig, Daniel Tubbenhauer, Arik Wilbert

We combinatorially describe the $2$ -category of singular cobordisms, called (rank one) foams, which governs the functorial version of Khovanov homology. As an application we topolo…

Generic $gl_{2}$ -foams, web and arc algebras

Michael Ehrig, Catharina Stroppel, Daniel Tubbenhauer

We define parameter dependent $gl_{2}$ -foams and their associated web and arc algebras, and verify that they specialize to several known $sl_{2}$ or $\mathfrak{gl…
