摘要:In this talk, we first introduce the quantum coordinate superalgebra  Aq(n) of type Q, derived from the quantized universal enveloping superalgebra of queer Lie superalgebra. Then referring to Manin's approach to the quantum general linear supergroup, we consider the extension problem from this  Aq(n) to a Hopf superalgebra, so-called the quantum queer supergroup. In particular, we confirm the existence of a special group-like element in such Hopf superalgebra, called the quantum queer Berezinian, as the queer super analogue of quantum determinant. Some questions unsolved will also be raised for further discussion. This is a joint work with Jiao Zhang.
