Title: A survey on the variational approach to the N-body problem


Abstract: In its full generality, the N-body problem of Celestial
Mechanics has challenged many generation of mathematicians. It is commonly
accepted, since the early works by H. Poincaré, that the periodic problem,
through its associated action spectrum, carries precious information on
the whole dynamics of a Hamiltonian system. Therefore, the problem of the
existence and the qualitative properties of periodic and other selected
trajectories for the N-body problem (from the classical celestial
mechanics point of view to more recent advances in molecular and quantum
models) has been extensively studied over the decades, and, more recently,
new tools and approaches have given a significant boost to the field. We
shall review some old an new results on the existence and
classification of selected trajectories of the classical N-body problem,
with an emphasis on new analytical and geometrical techniques.


Al termine del Colloquium seguira' un piccolo rinfresco in Sala Comune.
