Buongiorno,
vi segnalo il seguente mini-corso di Fisica Matematica che sara' tenuto da Alain Albouy (IMCCE, Paris) e consistera' di 4 lezioni di 2 ore ciascuna. Le prime 2 lezioni saranno martedi' 13 Dicembre ore 15-17 mercoledi' 14 Dicembre ore 10-12 in aula seminari, Dip. di Matematica.
Segue un breve abstract del corso. Cordialmente,
Giovanni Gronchi
--------------------------------------------------------------------- Title: Integrability in classical mechanics
Abstract: a phenomenological observation of conservative systems in classical mechanics is that they form two very distinct classes, the integrable ones and the non-integrable ones. But different authors however disagree about many examples. A basic example is the repulsive 3-body problem, considered by some as integrable, by others as non-integrable.
I will present Bruns and Poincare' classical non-integrability arguments for the 3-body problem, and more recent results. I will discuss several attempts of definition of integrability, and see what they give on the very basic examples of integrable systems in classical mechanics: central force, two-fixed centers, rigid body, etc. ---------------------------------------------------------------------
