The lecture will take place at 8-10a.m. on Monday in HG E5. The first lecture will be on 25.09.
For the exercise classes, see the section Exercise classes.
There will be Q&A sessions during the semester, see the section Q&A session.
In this lecture we treat problems in applied analysis. The focus lies on the simplest cases of three fundamental types of partial differential equations of second order: the Laplace equation, the heat equation and the wave equation.
