The aim of the conference is to highlight the use of various function spaces in the modern analysis of linear and nonlinear partial differential equations. The function spaces include Sobolev space-time spaces, Colombeau’s algebras, modulation spaces, symbol classes, path spaces, etc.

The program will include several survey lectures on the use of particular function spaces for various problems in PDEs.
