# Symplectic connections

@inproceedings{Bieliavsky2005SymplecticC, title={Symplectic connections}, author={Pierre Bieliavsky and Michel Cahen and Simone Gutt and John Howard Rawnsley and Lorenz J. Schwachhofer}, year={2005} }

This article is an overview of the results obtained in recent years on symplectic connections. We present what is known about preferred connections (critical points of a variational principle). The class of Ricci-type connections (for which the curvature is entirely determined by the Ricci tensor) is described in detail, as well as its far reaching generalization to special connections. A twistorial construction shows a relation between Ricci-type connections and complex geometry. We give a…

This note contains a short survey on some recent work on symplectic connections: properties and models for symplectic connections whose curvature is determined by the Ricci tensor, and a procedure to…

### Connections on contact manifolds and contact twistor space

- Mathematics
- 2010

In this paper we generalize the definition of symplectic connection to the contact case. It turns out that any odd-dimensional manifold equipped with a contact form admits contact connections and…

### Symplectic connections induced by the Chern connection

- Mathematics

Let (M;!) be a symplectic manifold and F be a Finsler struc- ture on M. In the present paper we deflne a lift of the symplectic two-form ! on the manifold TMn0, and flnd the conditions that the Chern…

### Critical symplectic connections on surfaces

- MathematicsJournal of Symplectic Geometry

The space of symplectic connections on a symplectic manifold is a symplectic affine space. M. Cahen and S. Gutt showed that the action of the group of Hamiltonian diffeomorphisms on this space is…

### Remarks on symplectic twistor spaces

We consider some classical fibre bundles furnished with almost complex structures of twistor type, deduce their integrability in some cases and study self-holomorphic sections of the general twistor…

There is constructed a family of Lie algebras that act in a Hamiltonian way on the symplectic affine space of linear symplectic connections on a symplectic manifold. The associated equivariant moment…

### SYMPLECTIC CONNECTIONS WITH A PARALLEL RICCI CURVATURE

- MathematicsProceedings of the Edinburgh Mathematical Society
- 2003

Abstract A symplectic connection on a symplectic manifold, unlike the Levi-Civita connection on a Riemannian manifold, is not unique. However, some spaces admit a canonical connection (symmetric…
