The Interplay Between Dispersive Partial Differential Equations and Fourier Analysis
Partial differential equations have always been a subject of fruitful interaction with Fourier analysis, starting precisely with the study of the heat equation. In the last few decades, nonlinear partial differential equations of hyperbolic and dispersive type, in particular, have been at the center of a significant new interplay and mutual progress between these two fields, through the works of prominent mathematicians like Tosio Kato, Charles Fefferman, Jean Bourgain, Carlos Kenig and Terence Tao.
In this talk, we will review some of the basic concepts and ideas that play a central role in this connection between techniques from Fourier analysis and properties of solutions of dispersive PDEs, covering topics like Strichartz estimates, smoothing effects, local and global well posedness of initial value problems at low regularity, among others.
