Canonical Transformations of Two-Dimensional Phase Space,e reader can o mit this and continue from the next chapter. It is worth noting that time-independent canonical transformations are an important tool to analyze the structure of a general singular theory.

Transformations, Symmetries and Noether Theorem,damental properties assumed for our space-time: homogeneity, isotropy, … . In this case, the Noether theorem states that conservation laws are consequences of these properties. For example, symmetry under spatial translations implies the conservation of the total momentum of a system.

Integral Invariants,ltonian equations. We discuss the basic Ponicaré-Cartan and Ponicaré integral invariants that represent line integrals of a special vector field defined on extended phase space. The integrals retain the same value for any closed contour taken on a given two-dimensional surface formed by solutions to

Potential Motion in a Geometric Setting,nge; for its history, see [34]. However, the traditional formulation (as a variational problem subject to the constraint that only the motions with fixed total energy are considered), remained problematic, as emphasized by V. Arnold (double citation): “In his Lectures on Dynamics (1842–1843), C. Jac

Transformations, Symmetries and Noether Theorem,evoted to discussion of the Noether theorem, which gives the relationship between the existence of conservation laws for the system in question, and symmetries of the associated action functional. The symmetries usually have a certain physical interpretation; in particular, they may reflect some fun
