Abstract: We consider periodic perturbations of a central force field having a rotational symmetry, and prove the existence of nearly circular periodic orbits. We thus generalize, in the planar case, some previous bifurcation results obtained by Ambrosetti and Coti Zelati. Our results apply, in particular, to the classical Kepler problem.

Abstract: The mathematical formulation of problems in dynamic fracture mechanics leads naturally to the study of the wave equation on domains which vary in time. We provide a notion of solution to the wave equation on a suitable class of time-dependent domains and show existence and uniqueness for the solutions of the Cauchy problem.
The results are obtained in collaboration with G. Dal Maso (SISSA, Trieste).

Abstract: In this talk, we give an overview on theoretical aspects of Optimal Transport for finitely many marginals motivated by a problem in Density Functional Theory. We aim to understand when a Monge-Kantorovich minimizer is of Monge-type in this setting.

Abstract: We prove homogenization results for obstacle problems in Orlicz-Sobolev spaces driven by p(.)-Laplace operator, as well as establish convergence of the coincidence sets.
