Constants of motion associated with alternative Hamiltonians
Gerardo F. Torres del Castillo
It is shown that if a non-autonomous system of first-order ordinary differential equations is expressed in the form of the Hamilton equations in terms of two different sets of…
Complete solutions of the Hamilton-Jacobi equation and the envelope method
G. F. Torres del Castillo, G. S. Anaya González
It is shown that the parameters contained in any two complete solutions of the Hamilton-Jacobi equation, corresponding to a given Hamiltonian, are related by means of a time-indepe…
Mapping of solutions of the Hamilton-Jacobi equation by an arbitrary canonical transformation
G. F. Torres del Castillo, H. H. Cruz Domínguez, A. de Yta Hernández +2
It is shown that given an arbitrary canonical transformation and an arbitrary Hamiltonian, there is a naturally defined mapping that sends any solution of the Hamilton-Jacobi (HJ)…
Generation of solutions of the Hamilton-Jacobi equation
G. F. Torres del Castillo
It is shown that any function , defined on the extended phase space, defines a one-parameter group of canonical transformations which act on any function $f(q_{…
