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.
