R-matrix realization of two-parameter quantum affine algebra $U_{r,s}(\widehat{gl}_n)$

arXiv:1604.06309 · doi:10.1016/j.algebra.2017.05.028

Abstract

We introduce the two-parameter quantum affine algebra $U_{r,s}(\widehat{gl}_n)$ via the RTT realization. The Drinfeld realization is given and the type A quantum affine algebra is proved to be a special subalgebra of our extended algebra.
