Graph products, ε-independence, and atoms

Abstract: In both classical and free probability theory, the central limit distribution can be modeled on a symmetric or free Fock space. The $q$-deformed Gaussians are the corresponding variables on ...

Deformations of Symplectic Foliations

In this talk, based on joint work with Stephane Geudens and Marco Zambon, we develop the deformation theory of symplectic foliations, i.e. regular foliations equipped with a leafwise symplectic form. ...

Symmetry breaking for semilinear elliptic problems in higher dimensions

In this talk, we present an existence result for semilinear elliptic problems of the form -Delta u + u = f(u), u > 0, u in H^1_0(A), where A denotes either an annulus or the exterior of a ball in R...

Zero viscosity limit for KAM solutions of the 2D Navier-Stokes equation

The question of the stability for solutions of the Euler and the Navier-Stokes equations in the vanishing viscosity regime is one of the most important problems in fluid dynamics. The goal of this tal...

Newhouse phenomena and universality in celestial mechanics

In \cite{McGeheestablemfold} McGehee introduced a compactification of the phase space of the restricted 3-body problem by gluing a manifold of periodic orbits ``at infinity''. Although from the dynam...

Generic quasi-periodic co-orbital motions in the planetary three-body problem

Numerous orbits in the solar system and in astrodynamics exhibit very peculiar motions. Their common feature is that they involve two moons or satellites orbiting around a much heavier central attract...

Andrej N. Kolmogorov, "The general theory of dynamical systems and classical mechanics" (1957): alla scoperta di una nuova grammatica metrica e spettrale per lo studio dei sistemi dinamici

Il testo "The general theory of dynamical systems and classical mechanics" (1957) di Andrej N. Kolmogorov rappresenta un momento cruciale nella storia della matematica del Novecento: non solo per l'av...
