Complex, symplectic and contact geometry, quantisation and interactions (ARC)

No funding agency referenced.

This research project involves three inter-linked subjects: quantisation, symplectic geometry and Kähler geometry. The research will follow two main  ...

Kahler Geometry

No funding agency referenced.

Extremal Kähler metrics, when they exist, are ''canonical'' representatives of their Kähler class. Their existence is conjecturaly equiavlent to the  ...

Definite connections

No funding agency referenced.

An SO(3)-connection on a 4-manifold is called definite if its curvature is non-zero on every tangent 2-plane. Given such a connection the corresponding ...

Complex geometry of flat bundles over hyperbolic 3-manifolds

No funding agency referenced.

The frame bundle X of a hyperbolic 3-manifold M is naturally a complex manifold with trivial canonical bundle. From this it is possible to give a holom ...

Topological symplectic manifolds

No funding agency referenced.

Study and comparison of different definitions of topological symplectic manifolds. Tentative constructions of examples.

Symplectic connections and symplectic geometry

No funding agency referenced.

Study of symplectic connections having certain curvature properties or solutions of a variational principle. Links with symplectic reduction and with p ...

Deformation quantization of symplectic and Poisson manifolds

No funding agency referenced.

Classification, group actions, homomorphisms,involutions,  representations.

Classes of homogeneous symplectic manifolds and of symplectic symmetric spaces

No funding agency referenced.

Study of conformal actions for homogeneous symplectic manifolds and symplectic symmetric spaces.
