Combining mathematical elements taken from calculus, analytic geometry and linear algebra, it provides a general and powerful approach to the investigation of physical phenomena, one based nevertheless on a specific and highly idealized conception of the way in which matter interacts.

This volume contains the proceedings of the International Conference on Hamiltonian Dynamical Systems; its contents reflect the wide scope and increasing influence of Hamiltonian methods, with contr

The Concept of Elastic Stress in Eighteenth-Century Mechanics: Some Examples from Eulerpts and ideas, on the one hand, and the application and extension of mathematical techniques on the other. The subject of continuum mechanics offers in this respect a very clear example. Combining mathematical elements taken from calculus, analytic geometry and linear algebra, it provides a general

Hemiplegia

Lax Pairs in the Henon-Heiles and Related Familiesns led to speculation, by some, that passing the test was a necessary condition for integrability. A subsequent infinite list of examples produced by A. Ramani et. al. [R-D-G] forced a qualification of this conjecture, and counterexamples to that qualification have now appeared (e.g. see [K-CR]).
