The Physicist‘s Conception of Natureich comes from the original article [.]) describes how the Liouville measure of a symplectic quotient varies. The second describes an oscillatory integral over a symplectic manifold equipped with a Hamiltonian group action and can be characterized by the slogan “Stationary phase is exact”.

The Physics Behind Semiconductor Technologyase space”, parametrizing position and momentum) is replaced by a vector space with an inner product; in other words, a Hilbert space (the “space of wave functions”). Functions on the manifold (“observables”) are replaced by endomorphisms of the vector space.

Symplectic Vector Spaces,y reviewing the notion of an almost complex structure on a vector space, we will see how the compatibility condition between the symplectic form and an almost complex structure gives rise to an inner product. In Sect. ., we will discuss the definition of symplectic manifolds, describe some of their

Hamiltonian Group Actions, the original example of a Hamiltonian flow, namely, Hamilton’s equations. In Sect. ., we will start by understanding what Hamiltonian vector fields and Hamiltonian functions are. In Sect. ., we will introduce a bracket on the set of smooth functions on a symplectic manifold which will satisfy the J

The Symplectic Structure on Coadjoint Orbits,irillov–Kostant–Souriau form). An example of an orbit of the adjoint action is the two-sphere, which is an orbit of the action of the rotation group .(3) on its Lie algebra .. Background information on Lie groups may be found in Appendix.

Toric Manifolds,een that the geometry of the moment polytope . is strongly related to the orbit structure of the action. We will study the case when there is as much symmetry as possible—when the torus is of largest possible dimension for the action to be effective. The main result of this chapter, due to Delzant,
