About

This course gives an introduction to the functional analytic treatment of partial differential equations.

Proseminar

The following problems should be prepared:

- Problem Set 1 (due 11.10): [Teschl] 10.18, 10.19, 10.21, 10.23
- Problem Set 2 (due 18.10): [Teschl] 10.24, 13.1, 13.3, 13.5
- Problem Set 3 (due 25.10): [Teschl] 13.7, 13.8, 13.9 [Evans] 5.10 Problem 3
- Problem Set 4 (due 8.11): [Evans] 5.10 Problem 4, 7, 8 (Instructions for 4: The absolutely continuous functions are the antiderivatives of integrable functions (see Theorem 11.49 in my notes). Now have a look at the hint for Problem 13.2 in my notes.)

- Problem Set 7 (due 29.11): [Evans] 6.6 Problem 2, 4 (Hint for 4: Find a solution of the homogenous problem)
- Problem Set 8 (due 6.12): [Evans] 6.6 Problem 5, 6
- Problem Set 9 (due 6.12): [Teschl] 7.3, 7.4, 7.5
- Problem Set 10 (due 10.1): [Teschl] 7.6, 7.7, 7.8, 7.9
- Problem Set 11 (due 17.1): [Teschl] 7.10, 7.11, 7.12 Please download the latest version of the notes!
