Teaching in the winter semester 2022/23
In the winter semester 2022/23 I will offer a seminar “Topics in functional analysis”. The objective of the seminar is to learn several topics which normally do not fit into a standard lecture course on functional analysis. Specifically, we will cover Sobolev spaces, fourier transform, locally convex spaces and, as crowning culmination, distributions. You can find more information in this announcement. Please send me an Email if you are interested in participating.
