Speaker: Stefano Marò  (Università di Pisa, Italy) Title: Chaotic motion in the breathing circle billiard Abstract: We consider the free motion of a point particle inside a circular billiard with periodically moving boundary, with the assumption that the collisions of the particle with the boundary are elastic so that the energy of the particle is not preserved. … Continue reading Stefano Marò (Università di Pisa, Italy)

Speaker: Isaia Nisoli  (Universidade Federal do Rio de Janeiro, Brazil) Title: A simple system presenting Noise Induced Order Abstract: In this talk I will present a family of one dimensional systems with random additive noise such that, as the noise size increases, the Lyapunov exponent of the stationary measure transitions from positive to negative. This … Continue reading Isaia Nisoli (Universidade Federal do Rio de Janeiro, Brazil)

Speaker: Anna Miriam Benini  (Università di Parma, Italy) Title: Infinite entropy for transcendental entire functions Abstract:  Defining entropy on noncompact metric spaces is a tricky business, since there are several natural and nonequivalent generalizations of the usual notions of entropy for continuous maps on compact spaces. By defining entropy for transcendental maps on the complex … Continue reading Anna Miriam Benini (Università di Parma, Italy)

Speaker: Carlangelo Liverani  (Università di Roma Tor Vergata, Italy) Title: Locating Ruelle-Pollicott resonances Abstract: We study the spectrum of transfer operators associated to various dynamical systems. Our aim is to obtain precise information on discrete spectrum. To this end we propose a unitary approach. We consider various settings where new information can be obtained following different … Continue reading Carlangelo Liverani (Università di Roma Tor Vergata, Italy)

Speaker: Andrea Venturelli  (Université d’Avignon, France) Title: Hyperbolic motion in the Newtonian N-body problem with arbitrary limit shape Abstract: We prove for the N-body problem the existence of hyperbolic motions for any prescribed limit shape and any given initial configuration of the bodies. The energy level h>0 of the motion can also be chosen arbitrarily. Our approach is … Continue reading Andrea Venturelli (Université d’Avignon, France)
