# Lecture plan

This is only a tentative plan which will be updated continuously.

The chapter numbers refer to the 10th edition of Kreyszig (references to the 9th edition in parentheses if they are different).

The video lectures refer (approximately) to the video lecture from 2011. Note that the order in which the different topics were discussed in 2011 differs from my lecture. 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!
