One of the great #mathematicians of the theory of integrable systems has passed away: Igor #Krichever (1950-2022) was instrumental in developing algebro-geometric methods to construct higher #genus solutions of #soliton equations 👉🏼 https://www.math.columbia.edu/~woit/wordpress/?p=13200 . He gave a plenary talk at the #ICM2022 📽️ https://www.youtube.com/watch?v=LliT-96R1mQ&t=1529s

la simulation du jour : équation de Schrödinger non-linéaire (#EDP SNL cubique focalisant) suivant que la donnée initiale soit Gaussienne ou un #Soliton l'amplitude va être conservée ou se disperser rapidement ...
