Categorification of infinite-dimensional -modules and braid group 2-actions I: tensor products
Benjamin Dupont, Grégoire Naisse
This is the first part of a series of two papers aiming to construct a categorification of the braiding on tensor products of Verma modules, and in particular of the Lawrence--Kram…

Odd Khovanov homology for tangles
Grégoire Naisse, Krzysztof Putyra
We extend the covering of even and odd Khovanov link homology to tangles, using arc algebras. For this, we develop the theory of quasi-associative algebras and bimodules graded ove…

Real Springer fibers and odd arc algebras
Jens Niklas Eberhardt, Grégoire Naisse, Arik Wilbert
We give a topological description of the two-row Springer fiber over the real numbers. We show its cohomology ring coincides with the oddification of the cohomology ring of the com…
