Fourier analysis and its applications to PDEs (Summer Semester 2019)
- Lecturer: JProf. Dr. Xian Liao
- Classes: Lecture (0157600), Problem class (0157610)
- Weekly hours: 1+1
This lecture (3SWS lecture+1SWS problem class) will last only for half the summer semester (i.e. from 23.04.2019 to 07.06.2019) and correspondingly the credit points (ECTS) will only be 2. The oral exam will take place on Tuesday 11.06.2019 and please send me email for the registration at latest 04.06.2019 if you would like to take the oral exam.
Here is the timetable for the lectures and the problem classes:

We are going to introduce the Fourier analysis theory and then to apply it to the study of various partial differential equations.
The Fourier analysis theory will include the following concepts:
-Fourier transform and Schwartz space, tempered distribution space
-Bernstein's inequality
-Littlewood-Paley decomposition
-Besov spaces and Sobolev spaces
-Paradifferential calculus
The following types of partial differential equations will be discussed:
-Transport equations
-Navier-Stokes equations
Prerequisites:
Basic concepts from functional analysis and real analysis, e.g. Lebesgue spaces, Hölder's inequality, Young's inequality, convolution.
