## Notes

Below are lecture notes for the course. They are a single file that will be updated after each lecture. Please keep in mind that these are notes that the professor writes for himself when preparing the lecture and should be complemented by a student's own class notes. Often more will be said in class than is in the notes. If you notice any errors in these notes (even small typos), please inform the professor. This helps him as well as your fellow students.
