Comments on Drinfeld Realization of Quantum Affine Superalgebra U q [gl(m|n ) (1) ] and its Hopf Algebra Structure
Abstract
By generalizing the Reshetikhin and Semenov-Tian-Shansky construction to supersymmetric cases, we obtain Drinfeld current realization for quantum affine superalgebra
U
q
[gl(m|n
)
(1)
]
. We find a simple coproduct for the quantum current generators and establish the Hopf algebra structure of this super current algebra.
