We show that for a special class of geometric quantizations with “small” quantum errors, the classical correspondence gives rise to an asymptotic projective unitary representation group Hamiltonian diffeomorphisms. As application, we get obstruction actions finitely presented groups.

Let X be a projective variety, homogeneous under a linear algebraic group. We show that the diagonal of X belongs to a unique irreducible component

The Annual Bio-Ontologies meeting (http://www.cs.man.ac.uk/ stevens/meeting03/) has now been running for 6 consecutive years, as a special interest group (SIG) of the much larger ISMB conference. It met in Brisbane, Australia, this summer, the first time it was held outside North America or Europe. The bio-ontologies meeting is 1 day long and normally has around 100 attendees. This year there w...
