Poincaré Compactification of Hamiltonian Polynomial Vector Fields). In the Poincaré compactification of some .-body problems the critical points which appear there are extremely degenerate. In this paper we focus our attention on generic properties of arbitrary Hamiltonian polynomial vector fields, especially at infinity.

A New Proof of Anosov’s Averaging Theorem normal form techniques adapted to a slightly generalized version of the DiPerna-Lions theory of generalized flows for ODEs . By specializing to the case of Hamiltonian vector fields, we obtain an interesting and somewhat surprising result for Hamiltonians of low regularity, as well as a reason for including this article in these proceedings.

(We do not assume Lax pairs and associated spectral curves are familiar to the reader.) Unfortunately, Lax pairs admitting useful spectral curves can be difficult to produce.

A 1: —1 Semisimple Hamiltonian Hopf Bifurcation in Vortex Dynamicsandidates for the vortex trails observed in experiments. In this note I will sketch a fresh approach to this old problem, which is based mainly on a systematic application of the Principle of Genericity, and Hamiltonian Bifurcation theory, , , , .
