Die Verschiedenen Koordinatensysteme. Section 2.2 investigates the precise definition of a symmetry group of a system of differential equations, which requires knowledge of how the group elements actually transform the solutions. The corresponding infinitesimal method rests on the important concept of “prolonging” a group action to th

Die Verschiedenen Koordinatensystemely states that the solutions which are invariant under a given .-parameter symmetry group of the system can all be found by solving a system of differential equations involving . fewer independent variables than the original system. In particular, if the number of parameters is one less than the num

Finite-Dimensional Hamiltonian Systems, of this vast subject, namely the interplay between symmetry groups, conservation laws and reduction in order for systems in Hamiltonian form. The Hamiltonian version of Noether’s theorem has a particularly attractive geometrical flavour, which remains somewhat masked in our previous Lagrangian framework.

Symmetry Groups and Conservation Laws,um. This basic principle constitutes the first fundamental result in the study of classical or quantum-mechanical systems with prescribed groups of symmetries. Noether’s method is the principal systematic procedure for constructing conservation laws for complicated systems of partial differential equations.
