On two-parameter deformations of
arXiv:math/0003040
Abstract
An elliptic two-parameter deformation of the (universal enveloping superalgebra of) affine Lie superalgebra is proposed in terms of free boson realization. This deformed superalgebra is shown to fit in the framework of infinite Hopf family of superalgebras, a generalization of the infinite Hopf family of algebras proposed earlier by the authors. The trigonometric and rational degenerations are briefly discussed.
