Some remarks about the faithfulness of the Burau representation of Artin--Tits groups
Asilata Bapat, Hoel Queffelec
We discuss the extension of the faithfulness question for the Burau representation of braid groups to the case of Artin--Tits groups. We prove that the Burau representation is not…
Gl2 Foam Functoriality and Skein Positivity
Hoel Queffelec
We prove full functoriality of Khovanov homology for tangled framed gl2 webs. We use this functoriality result to prove a strong positivity result for (orientable) surface skein al…
Movie moves for framed foams from multijet transversality
Hoel Queffelec, Kevin Walker
We use multijet transversality techniques to give a presentation by generators and relations of the categories of framed tangled webs and foams.
Polynomial link invariants and quantum algebras
Hoel Queffelec
The definition of the Jones polynomial in the 80's gave rise to a large family of so-called quantum link invariants, based on quantum groups. These quantum invariants are all contr…
Khovanov homology and categorification of skein modules
Hoel Queffelec, Paul Wedrich
For every oriented surface of finite type, we construct a functorial Khovanov homology for links in a thickening of the surface, which takes values in a categorification of the cor…
Extremal weight projectors II
Hoel Queffelec, Paul Wedrich
In previous work, we have constructed diagrammatic idempotents in an affine extension of the Temperley-Lieb category, which describe extremal weight projectors for sl(2), and which…
