Transformation Properties of the Lagrange— D’Alembert Variational Principle: Conservation Laws of Noof conservat ive and purely nonconservative dynamical systems. The basic idea of this approach is to consider the transformation properties of the Lagrange-D’Alembert principle with respect to the infinite simaltransform at ion of the generalized coordinates and time. It is of interest to note that

The Hamiltonian Variational Principle and Its Applicationse is based upon the . characteristics of motion; that is, the relations between its scalar and vector characteristics are considered simultaneously in one particular inst ant of time. The problem of describing the global characteristics of motion has been reduced to the integration of differential e

Einleitung und Problemstellung,t form that is not connected to any privileged coordinate system. To accomplish this goal we turn first to the Lagrange-D’Alembert differential variational principle, whose applications are very wide and encompass holonomic and nonholonomic dynamical systems and also conservative and purely nonconse
