“Optimal Transport in Cosmology and the Evolution of Large-Scale Structure”
Lunedì 19 Febbraio 2024, ore 10:00 - Aula 1A150 - Sabino Matarrese (Università degli Studi di Padova), Enzo Branchini (Università di Genova), Elena Sarpa (SISSA)
Optimal Transport methods, originally introduced to address very practical problems, have evolved into a rich field of research with applications in several fields, includiong some unexpected ones like cosmology. Indeed, they have emerged as precious tools in cosmology, providing insights into the formation and evolution of cosmic structures. In these lectures we will review the basic concepts emphaszing the significance of these methods in understanding the build-up of cosmic structures. Notably, there is a meaningful connection between optimal transport methods and Jim Peebles’ cosmological least action principle, which will be also reviewed.
