Seminario di Fisica Matematica

Mercoledì 22 Maggio 2024 alle ore 14:00, Giuseppe Gaeta (Università di Milano) terrà il seminario di Fisica Matematica dal titolo "RG & PDEs".

Abstract:
I discuss how ideas stemming from Renormalization Group (first presented by Goldenfeld, Martin, Oono & Liu and by Bricmont & Kupiainen – and used by the Japanese school in the analysis of Dynamical Systems, following a seminal paper by Iwasa & Nozaki) can be implemented in the analysis of (nonlinear) PDEs, in particular concerning their asymptotic solutions for long time and/or at large spatial scales. This approach is based on the (Cartan) geometrical theory of PDEs, and on the (asymptotic) symmetry analysis of these.
I will also present some very recent advances concerning a simple computational approach to this problem, for evolution PDEs and a certain class of would-be symmetries.

Il seminario si svolgerà in presenza presso il Dipartimento di Matematica e Fisica -  Via della Vasca Navale 84 -  Aula A.
