Math 825: Selected Topics in Functional Analysis . Short description: This course will cover topics in Harmonic analysis and PDE focusing on some of the most recent developments. The plan is to discuss the concept of wave packets and their applications to time-frequency analysis and dispersive PDE, convex integration with applications in nonlinear evolution equations, the d-bar method in

Hormander studied the singularities of distributional solutions to such a PDE and how they propagate. This in turn leads to an a regularity theorem for a compactly supported distributional solution on a bounded open domain.

This introduction to the theory of nonlinear hyperbolic differential equations, a revised and extended version of widely circulated lecture notes from 1986, starts from a very elementary level with standard existence and uniqueness theorems for ordinary differential equations, but they are at once supplemented with less well-known material, required later on.

Review by: L Cattabriga. Hormander Hypoellipticity condition is a sufficient condition for proving regularity of fundamental solutions of linear PDE's. A brief review of the material covered in the first lectured will be given followed by some of the main points of the proof. of PDE (most obviously in the study of harmonic functions, which are solutions to the PDE ∆u= 0, but in fact a very wide class of PDE is amenable to study by harmonic analysis tools), and has also found application in analytic number theory, as many functions in … Chapter 3.
