A Remark on the FRTS Realization and Drinfeld Realization of Quantum Affine Superalgebra U q (o\({\hat s} \)sp(1,2))

Abstract

In this Letter, we present the hidden symmetry behind the Faddeev–Reshetikhin–Takhtajan–Semenov–Tian–Shansky (FRTS) realization of quantum affine superalgebras U(o\({\hat s} \)sp(1,2)) and add the q-Serre relation to the Drinfeld realization of U(o\({\hat s} \)sp(1,2)), derived from the FRTS realization.
