Quantum Sugawara operators in ${\mathrm{U}}_q({\widehat{\mathfrak{gl}}}_{M|N})$

Naihuan Jing, Ming Liu, Jian Zhang

We construct Sugawara operators for the quantum affine superalgebra ${\mathrm{U}}_q({\widehat{\mathfrak{gl}}}_{M|N})$ in an explicit form which generalizes the results given in \cite{J…
