The prime spectrum of the Drinfeld double of the Jordan plane
K. A. Brown, J. T. Stafford
The Hopf algebra which is the subject of this paper can be viewed as a Drinfeld double of the bosonisation of the Jordan plane. Its prime and primitive spectra are co…
Quantum Hamiltonian Reduction for Polar Representations
G. Bellamy, T. Levasseur, T. Nevins +1
Let be a reductive complex Lie group with Lie algebra and suppose that is a polar -representation. We prove the existence of a radial parts map $\mathrm{r…
Invariant holonomic systems on symmetric spaces and other polar representations
G. Bellamy, T. Nevins, J. T. Stafford
Let be a symmetric space over a connected reductive Lie algebra , with Lie algebra and discriminant . A fundamental object is the invarian…
Ring-theoretic blowing down II: Birational transformations
D. Rogalski, S. J. Sierra, J. T. Stafford
One of the major open problems in noncommutative algebraic geometry is the classification of noncommutative projective surfaces (or, slightly more generally, of noetherian connecte…
Some Noncommutative Minimal Surfaces
D. Rogalski, S. J. Sierra, J. T. Stafford
In the ongoing programme to classify noncommutative projective surfaces (connected graded noetherian domains of Gelfand-Kirillov dimension three) a natural question is to determine…
