Almost-periodic solutions for the NLS with parameters

23 / 01 / 2019

Speaker: Michela Procesi, University of Roma Tre
Time: 16:00
Place: Aula T1 (2n pis), Facultat de Matemàtiques i Informàtica, UB

Summary:

I shall discuss a recent result with L. Biasco and J. Massetti on the existence of almost-periodic solutions for the NLS on the circle with external parameters. After discussing the (very few) known results I shall describe our strategy, which is quite flexible and can be applied also for the construction of non maximal tori. Time permitting I shall discuss also the connection with exponential/subexponential stability for small initial data.
