On the existence and regularity of minimizers of attraction-repulsion energies
speaker: Aldo Pratelli (Università di Pisa)abstract: Since Gamow introduced the celebrated liquid drop model, in the 1930's, there has been a deep interest between Physics and Mathematics on the minimization of various forms of energy, usually showing the so-called attraction-repulsion effect, that is, particles attract each other if they are far away, but they repulse each other when they become too close. There have been in the decades, and particularly in the last years, severals specific examples and generalizations. In this talk, we aim to give an overall view of some of the main problems, discussing known properties and open questions. We will range from classical results to very recent ones. Some of the results are obtained in different collaborations with D. Carazzato, N. Fusco, and M. Novaga.
