Non-commutative invariant theory
Seminar Room 1, Newton Institute
AbstractWe define a (non-commutative) quantum analogue of the coordinate ring of a finite dimensional module of a quantum group, which in many (but not all) cases is a flat deformation of the classical coordinate ring. We prove a quantum analogue of the first fundamental theorem of invariant theory in a form which generalises the classical cases. This is joint work with R. Zhang and H. Zhang.
If it doesn't, something may have gone wrong with our embedded player.
We'll get it fixed as soon as possible.
