چکیده
The automorphism group of a locally conformal symplectic structure is studied. It is shown that this group possesses essential features of the symplec-tomorphism group. By using a special type of cohomology the ux and Calabi homomorphisms are introduced. The main theorem states that the kernels of these homomorphisms are simple groups, for the precise statement see chapter 7. Some of the methods used, may also be interesting in the symplectic case.

متن کاملReduction for Locally Conformal Symplectic Manifolds
It is shown how one can do symplectic reduction for locally conformal symplectic manifolds, especially with an action of a Lie group. This generalizes well known procedures for symplectic manifolds to the slightly larger class of locally conformal symplectic manifolds. The whole setting is very conformally invariant.
متن کاملReductions of Locally Conformal Symplectic Structures and De Rham Cohomology Tangent to a Foliation
where ω is a closed 1-form. ω is uniquely determined by Ω and is called the Lee form of Ω. (M,Ω, ω) is called a locally conformal symplectic manifold. If Ω satisfies (1) then ω|Ua = d(ln fa) for all a ∈ A. If fa is constant for all a ∈ A then Ω is a symplectic form on M . The Lee form of the symplectic form is obviously zero. Locally conformal symplectic manifolds are generalized phase spaces o...
متن کاملLocally conformal symplectic nilmanifolds with no locally conformal Kähler metrics
We report on a question, posed by L. Ornea and M. Verbitsky in [32], about examples of compact locally conformal symplectic manifolds without locally conformal Kähler metrics. We construct such an example on a compact 4-dimensional nilmanifold, not the product of a compact 3-manifold and a circle.
متن کاملWhat kinds of dynamics are there? Lie pseudogroups, dynamical systems, and geometric integration
We classify dynamical systems according to the group of diffeomorphisms to which they belong, with application to geometric integrators for ODEs. This point of view unifies symplectic, Lie group, and volume-, integral-, and symmetrypreserving integrators. We review the Cartan classification of the primitive infinite-dimensional Lie pseudogroups (and hence of dynamical systems), and select the c...
