Higher Tensor Product for sl2 and Webster algebras

Mark Ebert, Raphael Rouquier

We construct a model for the tensor product of the regular 2-representation of the enveloping algebra of $sl_{2}^{+}$ with the vector 2-representation, based on the $\infty$ …

A local $gl_{1∣1}$ -action on odd Khovanov homology

We show that odd Khovanov homology carries an action of the super Lie algebra $gl_{1∣1}$ , given extra choice of markings on the link. Moreover, we show that this action…
