Factoring the Lunar Problem: Geometry, Dynamics, and Algebra in the Lunar Theory from Kepler to Claiaratus could get top-heavy. Tycho Brahe, for one was bothered by geometrical complication. Here is his theory (Fig. 1.1), developed during the 1590s, for the two main inequalities in the Moon’s longitude.

In this paper we focus our attention on generic properties of arbitrary Hamiltonian polynomial vector fields, especially at infinity.

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.
