The statement ii clearly holds as well for more general fields K R. The appropriate concept of maps for differentiable manifolds are those maps which are compatible with the differential structures.

## An Introduction to Symplectic Geometry

Let M and N be differentiable manifolds of dimensions p and q, respectively. This definition can easily be brought into agreement with the definitions which often appear in elementary textbooks. Therefore, for all g E Gm and u, v, w E 7,n M. This will assure the plausible existence of a diffeomorphism Fl: Kiihler manifolds A Kuhler manifold is, roughly speaking, a complex n-manifold thus the transformation functions between the charts are holomorphicequipped with a Kiihler metric, that is, a hernitian metric for which the associated 2 form w is closed.

One may derive, from a metric fundamental tensor, the Riemannian curvature tensor which is required for the formulation of the theory of general relativity. So let w E Z2 g be a closed form on G, and set l: Here it can be seen that the vanishing of f2 is independent of the choice of the d-frame.

A connection V on a differentiable manifold M is a map V: In this case the important tools are the groups SL2 Rthe Heisenberg group Heis2n Rthe Symplecttic group Ga R as a semidirect product of the Heisenberg and symplectic groups and their associated Lie algebras. Intrdouction collection of all sections will be denoted by I’ E, U K vector space. Symplectic Manifolds 46 order to introduce them, we need the material of Section 1.

In any case, it will soon be clear that the physically most important examples of contact manifolds arise as hypersurfaces of constant energy in Hamiltonian systems or from the treatment of time-dependent Hamiltonian functions. Now from Theorem 3. This means that in order to describe the state of the system by vi, the quantities f must have a fixed value a, for which vi is an eigenvector with eigenvalue a.

For r, we have P r v1, This is again a Analogously one can, for every r E No, define the sections of class Cr.

The interpretation of TmM as the space of derivatives. These ideas have revolutionized the subject.

Hardcoverpages. Separate different tags with a comma. Let Lq T,W be the K vector space of q-linear maps f: For associated to w, given as described above by Im for T. We will later examine for which f E. Publication Month and Year: Graduate students and research mathematicians interested in differential geometry. This tensor is sympletic a metric or a Riemannian fundamental tensor, when a the matrix gi1 x for all x E cp U is symmetric and positive definite, b the functions gil x are all differentiable, and c between the function systems of compatible charts, there is the following relationship between the transformation functions: The following examples should make clear what may be confusing at this first glance.

The goal of the book is to provide an entrance into a fascinating area linking several mathematical disciplines and parts of theoretical physics.

Because of the compactness of SI. Lists What are lists? For each m E M, beometry a scalar productin TmM be given-that is, a symmetric positive definite bilinear form. The reader should pay particular attention to this last relationship. The metric u on E fixes a volume form dr. This is in sharp contrast to the situation with Riemannian manifolds, whose definition is otherwise xiii Preface somewhat parallel to that of the symplectic manifolds.

### An Introduction to Symplectic Geometry

We will also give some details in Section 5. The collection of symplectic automorphisms forms a group under the usual composition, called the symplectic group of V; w and denoted Sp V. Here, differentiable will mean infinitely differentiable, although in many cases this will be stronger than needed. Then the reduction described in Theorem 4. Gompf and Andrds I. Subspaces of symplectic vector spaces Let W be a k-dimensional linear subspace of the 2n-dimensional symplectic space V, w. The orbits of this action are called coadjoint orbits and can under known conditions be made into symplectic manifolds. When M C R9 is a submanifold, this definition simplifies as follows: Then see Appendix D an irreducible unitary representation of G 7r: This will then offer yet another means for introducing one of the central concepts of the field.

Here properly means the following:
