Universal $R$ -matrix of double parameter quantum affine algebra $U_{q, Q} (s l_{2}^)$

Fengchang Li, Masatake Maruyama, Hiroyuki Yamane

We give the explicit formula of the universal $R$ -matrix of a double parameter (or two-parameter, or multi-parameter) quantum affine algebra of type $A_{1}^{(1)}$ . For $N$ …

On the structure of quantum affine superalgebra $U_{v} (A (0, 2)^{(4)})$

Fengchang Li

We research $U_{v} (A (0, 2)^{(4)})^{+}$ defined by quantum Serre relations, when $v$ is not a root of unity. We prove that $U_{v} (A (0, 2)^{(4)})^{+}$ is isomorphic to a Nichols algebr…
