Complex dynamics and bifurcations in a Hamiltonian system having a transversal homoclinic orbit to a saddle focus.

Chaos, 1991
A Hamiltonian system having a saddle-focus singular point with a transversal homoclinic orbit is considered. The bifurcations that occur upon a variation of the Hamiltonian are studied.

New Types of the Lie Symmetries and Conserved Quantities for a Relativistic Hamiltonian System

, 2003
For a relativistic Hamiltonian system, two new types of the Lie symmetries and conservation laws are given under infinitesimal transformations of groups.

Chaos in hamiltonian systems

Proceedings of the Royal Society of London. A. Mathematical and Physical Sciences, 1987
Modern developments in hamiltonian dynamics are described, showing the change of view that has occurred in the last few decades. The properties of mixed systems, which exhibit both regular and chaotic motion are contrasted with those of the integrable systems, for which the motion is entirely regular, and of Anosov systems, for which it is almost ...

Symmetry in a constrained Hamiltonian system with singular higher-order Lagrangian

, 1991
For a canonical formalism with a higher-order derivative, the corresponding generalized first Noether theorem (GFNT) for a constrained Hamiltonian system and the generalized Noether identities (GNI) for a system with a non-invariant action integral are ...
