Billel Guelmame ENS Lyon Singularity formation and global weak solutions to the Serre–Green–Naghdi equations with surface tension Séminaire A3 Résumé

In this talk, we explore the Serre–Green–Naghdi equations, which describe shallow-water waves while considering the influence of surface tension. These equations are locally (in time) well-posed. We identify a class of smooth initial data, leading to the development of singularities in finite time for the corresponding strong solutions. Additionally, we demonstrate the existence of global weak solutions for small-energy initial data.
