Two-parameter Quantum Affine Superalgebra $U_{p,q}\widehat{(gl(1|1))}$ and Its Drinfeld's Realization

Abstract

Using super RS construction method and Gauss decomposition, we obtain Drinfeld's currents realization of two-parameter quantum affine superalgebra $U_{p,q}\widehat{(gl(1|1))}$ and get co-product structure for these currents.
