A Remark On the FRTS realization and Drinfeld Realization of Quantum Affine Superalgebra $U_q(\widehat{osp}(1,2))$

In this paper, we present the hidden symmetry behind the Faddeev-Reshetikhin-Takhtajan-Semenov-Tian-Shansky realization of quantum affine superalgebras $U_q(\widehat{osp}(1,2))$ and add the q-Serre relation to the Drinfeld realization of $U_q(\widehat{osp}(1,2))$ (math.QA/9712011) derived from the FRTS realization.
