摘要：Using quantum differential operators, we construct a quantum gl_{m|n} supermodule structure on a certain polynomial superalgebra. We then extend this representation to its formal power series algebra which contains a submodule isomorphic to the regular representation of this quantum supergroup. In this way, we obtain a new presentation for quantum gl_{m|n} by a basis together with explicit multiplication formulas by generators. This allows us to introduce the canonical basis for the +-part.
On the other hand, we extend the supermodule structure on the polynomial superalgebra to a (partial) Laurent polynomial superalgebra which induces the regular representation of the modified quantum gl_{m|n}. In this way, a new presentation and its canonical basis theory are developed for this modified case.
This is joint work with Haixia Gu and Zhongguo Zhou.
