Monica Musso – The Liquid Drop Model: From Minimizers to Non-Spherical Equilibria

Amphithéâtre Choquet-Bruhat – IHP 11 Rue Pierre et Marie Curie, Paris

Speaker: Monica Musso, University of Bath Abstract for the mini course: Introduction to the Liquid Drop Model: Minimizers, Stability and Nonexistence The liquid drop model, introduced by Gamow to describe atomic nuclei, is a classical problem in the calculus of variations involving the competition between surface tension, which favours compact shapes, and Coulomb repulsion, which favours spreading and fragmentation. In this introductory lecture, I will present the mathematical formulation of the model and review some fundamental results concerning the existence and geometry of energy minimizers. Particular attention will be given […]

ENS-Data Science colloquium – Pierre Gentine (Columbia University) : Lost in latent land

Amphi Jean Jaurès 29 rue d'Ulm, PARIS, France

Machine learning and artificial intelligence have been revolutionizing weather and climate modeling and data analysis over the past few years. However, it remains unclear how much understanding has been gained from those models, even though they are reaching unprecedented accuracy. Through the study and analysis of carefully chosen latent spaces, I will demonstrate how we can get new understanding on the terrestrial water and carbon cycle as well as on atmospheric processes, specifically on convection. Those latent spaces can also be used to better characterize complex stochastic processes such as […]
