We generalize results of Lee, Gornik and Wu on the structure of deformed colored sl(N) link homologies to the case of non-generic deformations. To this end, we use foam technology to give a completely combinatorial construction of Wu's deformed colored sl(N) link homologies. By studying the underlying deformed higher representation theoretic structures and generalizing the Karoubi envelope approach of Bar-Natan and Morrison we explicitly compute the deformed invariants in terms of undeformed…

Symmetric Khovanov-Rozansky link homologies
We provide a finite dimensional categorification of the symmetric evaluation of $\mathfrak{sl}_N$-webs using foam technology. As an output we obtain a symmetric link homology theory categorifying the
A deformation of Robert-Wagner foam evaluation and link homology
We consider a deformation of the Robert-Wagner foam evaluation formula, with an eye toward a relation to formal groups. Integrality of the deformed evaluation is established, giving rise to state
Anchored foams and annular homology
We describe equivariant SL(2) and SL(3) homology for links in the solid torus via foam evaluation. The solid torus is replaced by 3-space with a distinguished line in it. Generators of state spaces
gl(2) foams and the Khovanov homotopy type
The Blanchet link homology theory is an oriented model of Khovanov homology, functorial over the integers with respect to link cobordisms. We formulate a stable homotopy refinement of the Blanchet
Evaluations of annular Khovanov-Rozansky homology
Author(s): Gorsky, Eugene; Wedrich, Paul | Abstract: We describe the universal target of annular Khovanov-Rozansky link homology functors as the homotopy category of a free symmetric monoidal
Transverse link invariants from the deformations of Khovanov 𝔰𝔩3–homology
In this paper we will make use of the Mackaay-Vaz approach to the universal $\mathfrak{sl}_3$-homology to define a family of cycles (called $\beta_3$-invariants) which are transverse braid
Upsilon-like concordance invariants from 𝔰𝔩n knot cohomology
We construct smooth concordance invariants of knots which take the form of piecewise linear maps from [0,1] to R, one for each n greater than or equal to 2. These invariants arise from sl(n) knot
Categorified N invariants of colored rational tangles
We use categorical skew Howe duality to find recursion rules that compute categorified slN invariants of rational tangles colored by exterior powers of the standard representation. Further, we offer
A family of link concordance invariants from perturbed sl(n) homology
We define a family of link concordance invariants $\left\{ s_n \right\}_{n=2,3, \cdots}$. These link concordance invariants give lower bounds on the slice genus of a link $L$. We compute the slice


Generic deformations of the colored sl(N)-homology for links
We generalize the works of Lee [arXiv:math/0210213v3] and Gornik [arXiv:math/0402266v2] to construct a basis for generic deformations of the colored sl(N)-homology defined in [arXiv:1002.2662v1]. As
Clasp technology to knot homology via the affine Grassmannian
We categorify all the Reshetikhin–Turaev tangle invariants of type A. Our main tool is a categorification of the generalized Jones–Wenzl projectors (a.k.a. clasps) as infinite twists. Applying this

It is proved that the homotopy type of this chain complex is invariant under Reidemeister moves and decategorifies to the Reshetikhin-Turaev sl(N) polynomial of links colored by exterior powers of the defining representation.
Khovanov homology is a skew Howe 2-representation of categorified quantum sl(m)
We show that Khovanov homology (and its sl(3) variant) can be understood in the context of higher representation theory. Specifically, we show that the combinatorially defined foam constructions of
The universal sl3–link homology
We define the universal sl3 –link homology, which depends on 3 parameters, following Khovanov’s approach with foams. We show that this 3–parameter link homology, when taken with complex coefficients,
Equivariant sl(n)-link homology
For every positive integer $n$ we construct a bigraded homology theory for links, such that the corresponding invariant of the unknot is closely related to the U(n)-equivariant cohomology ring of
Khovanov's homology for tangles and cobordisms
We give a fresh introduction to the Khovanov Homology theory for knots and links, with special emphasis on its extension to tangles, cobordisms and 2-knots. By staying within a world of topological
Quadruply-graded colored homology of knots
We conjecture the existence of four independent gradings in colored HOMFLYPT homology, and make qualitative predictions of various interesting structures and symmetries in the colored homology of
The Karoubi envelope and Lee’s degeneration of Khovanov homology
We give a simple proof of Lee’s result from [5], that the dimension of the Lee variant of the Khovanov homology of a c ‐component link is 2 c , regardless of the number of crossings. Our method of
Equivariant colored sl(N)-homology for links
We construct an equivariant colored sl(N)-homology for links, which generalizes both the colored sl(N)-homology defined by the author and the equivariant sl(N)-homology defined by Krasner. The
