Tid: Ti 2018-05-22 kl 13.15

Föreläsare: Gigliola Staffilani, MIT

Plats: E3

The aim of this third lecture is to analyze the long time instability of the zero solution of the 2D periodic defocusing cubic NLS, while outlining the differences between the dynamics on rational versus irrational tori. In particular we will analyze the structure of the resonance sets in these two different set ups. This instability can also be related to well known phenomena such as energy transfer and forward cascades.
