A local -action on odd Khovanov homology
Mark Ebert, Léo Schelstraete
We show that odd Khovanov homology carries an action of the super Lie algebra , given extra choice of markings on the link. Moreover, we show that this action…

A basis and Schur-Weyl duality for the loop Hecke algebra
Geoffrey Janssens, Abel Lacabanne, Léo Schelstraete +1
The loop Hecke algebra is a generalization of the Hecke algebra to the loop braid group, introduced by Damiani, Martin and Rowell. We give a new presentation of the loop Hecke alge…

Rewriting modulo in diagrammatic algebras and application to categorification
Léo Schelstraete
We develop a rewriting theory modulo suitable for higher linear structures. In particular, the theory is suited for diagrammatic algebras as they appear in categorification, repres…
