# Lecture plan

This is a tentative schedule, which will be updated continuously.

The chapter numbers refer to the 10th edition of Kreyszig.

The video lectures refer (approximately) to the video lectures from 2011, which should only be considered as support, and not as replacement of the class lectures. Note that the order in which the different topics were discussed in 2011 differs from the lectures. Also, there will probably be small differences in content. That is, it is possible that some of the topics discussed in 2011 will not be part of this year's lecture and vice versa. Be aware of these differences in particular when preparing for the exam!
