Abstract:

Using quantum differential operators, we construct a super representation of $U_{\boldsymbol {\upsilon }}(\mathfrak {gl}_{m|n})$ on a certain polynomial superalgebra. We then extend the representation to its formal power series algebra which contains a $U_{\boldsymbol {\upsilon }}(\mathfrak {gl}_{m|n})$-submodule isomorphic to the regular representation of $U_{\boldsymbol {\upsilon }}(\mathfrak {gl}_{m|n})$. In this way, we obtain a presentation of $U_{\boldsymbol {\upsilon }}(\mathfrak {gl}_{m|n})$ by a basis together with explicit multiplication formulas of the basis elements by generators.
