Variational And Local Methods In The Study Of Hamiltonian Systems – Proceedings Of The Workshop [PDF ebook] 

In this volume, various ideas about Hamiltonian dynamics were discussed. Particular emphasis was placed on mechanical systems with singular potentials (such as the N-Body Newtonian problem) and on their special features, although important aspects of smooth dynamics were also discussed, from both the local point of view and the point of view of global analysis.
