A Normal Form without small divisors
Gabriella Pinzari
Following the techniques of [4], we formulate a Normal Form Lemma suited to close to be integrable Hamiltonian systems where not all the coordinates are action angles. The Lemma tu…

An analysis of the Sun-Earth-Asteroid systems based on the two-centre problem
Gabriella Pinzari
We propose a new analysis of the two--centre problem particularly suited to be used as a basis to study the dynamics of Sun--Earth--Asteroid systems. Our method, based on a tricky…
