Functional Analysis

Nonlinear PDEs I

Winter 2015/2016


Mondays and Thursdays 10–12, SR 1.008
Prof. Dr. J. J. L. Velázquez


Tuesday 14–16, room N0.003

Wednesday 14–16, room SR 0.011


The course is completed by an exam on 15./16.02.2016 and 15./16.03.2016. Slots for the first date will be allocated in due course.


In order to sit the exam students have to get at least 50% of the overall marks of the problem sheets as requirement for passing the classes.

Synopsis and Prerequisites

The course covers basic theory (existence, uniqueness, regularity) for weak solutions of nonlinear elliptic and parabolic PDEs.


A sound knowledge of linear PDEs and functional analysis is essential.

Problem sheets

Problem sheets are handed out in the lecture on Thursdays and are available below. Solutions may be submitted in groups of two students who attend the same tutorial and are collected on Thursdays during the lecture.
