RLL-realization and its Hopf superalgebra structure of Up,q(gl̂(m|n))

In this paper we extend the Reshetikhin–Semenov–Tian–Shansky formulation of quantum affine algebras to the two-parameter quantum affine superalgebra Up,q(gl̂(m|n)) and obtain its Drinfeld realization. We also derive its Hopf algebra structure by providing Drinfeld-type coproduct for the Drinfeld gen...

Description
Summary:In this paper we extend the Reshetikhin–Semenov–Tian–Shansky formulation of quantum affine algebras to the two-parameter quantum affine superalgebra Up,q(gl̂(m|n)) and obtain its Drinfeld realization. We also derive its Hopf algebra structure by providing Drinfeld-type coproduct for the Drinfeld generators.
