FUNCTION SPACES AND POTENTIAL THEORY
Quick information: In summer term 2020, I will give a graduate lecture on 'Function Spaces & Potential Theory' within the selected topics series. By the recent outbreak of the corona virus, the lectures will
-
take place online. As soon as I have more information, the precise platform will be communicated on this website. We will make use of Zoom - the ID and the password are available on request.
-
be available online as videos. The lectures themselves will be broadcasted and provided online afterwards; there will be extensive lecture notes and additional slides.
-
These rules apply at least until we are allowed to return to the usual setting - in any case, to have a consistent course framework, all lectures will be provided online (even though we might restart as usual at some later point).
​
Target audience: The course itself is designed for Master students (and onwards). Bachelor students (3rd year/6th term of study) are also welcome. The necessary prerequisites for the course are as follows:
-
Foundational modules: Analysis 1 - 3, Linear Algebra 1,2,
-
Advanced modules: Introduction to PDE (or Nonlinear PDE 1 - at least one of the two), Functional Analysis & PDEs.
​
Main references: The course will not follow a particular textbook as I also aim to report on some more recent developments as the course evolves. A preliminary background reading list is as follows:

Lectures, slides & lecture notes
The lecture notes are available here (current as of May, 18).
​
Lectures 6-8 (typing is not quite finished) are available here.
​
Lecture 9 is available here.
Problem Sets
There are non-obligatory problem sets. By request, we might have a discussion session. The precise date will be will be set up by a Doodle poll.

-
Problem Set 1 (May 03 - May 17)
-
Problem Set 2 (June 15- June 29)
Useful background material
