Maximally extended sl(2|2), q-deformed d(2,1;epsilon) and 3D kappa-Poincaré
Niklas Beisert, Reimar Hecht, Ben Hoare
We show that the maximal extension sl(2) times psl(2|2) times C3 of the sl(2|2) superalgebra can be obtained as a contraction limit of the semi-simple superalgebra d(2,1;epsilon) t…

Maximally extended sl(2|2) as a quantum double
Niklas Beisert, Marius de Leeuw, Reimar Hecht
We derive the universal R-matrix of the quantum-deformed enveloping algebra of centrally extended sl(2|2) using Drinfeld's quantum double construction. We are led to enlarging the…
