Drinfeld second realization of the quantum affine superalgebras of $D^{(1)}(2,1;x)$ via the Weyl groupoid

Understand

We obtain Drinfeld second realization of the quantum affine superalgebras associated with the affine Lie superalgebra $D^{(1)}(2,1;x)$.

• Our results are analogous to those obtained by Beck for the quantum affine algebras.
• Beck's analysis uses heavily the (extended) affine Weyl groups of the affine Lie algebras.
• In our approach the structures are based on a Weyl groupoid.
