Colored Khovanov homology theories at prime roots of unity

You Qi, Louis-Hadrien Robert, Joshua Sussan +1

We equip Khovanov's colored -homology groups with a degree-2 derivation. Over a field of characteristic , the derivation specializes to a -nilpotent diffe…

Infinitesimal sl(2)-symmetries on the equivariant skein lasagna module

You Qi, Louis-Hadrien Robert, Joshua Sussan +2

We construct an sl(2)-action on the equivariant skein lasagna module.

A foamy approach to Soergel bimodules

Mikhail Khovanov, Louis-Hadrien Robert, Emmanuel Wagner

The aim of this short note is to establish a 2-equivalence between a certain 2-category of foams and that of singular Soergel bimodules of type A.

MOY calculus in type D

Elijah Bodish, Louis-Hadrien Robert, Emmanuel Wagner

We define a positive state sum for webs "of type D". These webs are graphs which mimic morphisms in the category of finite-dimensional quantum so(2N)-modules. From the state sum, w…

Remarks on some infinitesimal symmetries of Khovanov--Rozansky homologies in finite characteristic

You Qi, Louis-Hadrien Robert, Joshua Sussan +1

We give a new proof of a theorem due to Shumakovitch and Wang on base point independence of Khovanov--Rozansky homology in characteristic . Some further symmetries of $\mathfrak…

State sums for some super quantum link invariants

Louis-Hadrien Robert, Emmanuel Wagner

We present state sums for quantum link invariants arising from the representation theory of . We investigate the case of the -th exterior power of the…
