Here is the syllabus.
Here are the course notes. Note: these are automatically re-TeX-ed and updated daily. This means that the date on the document does not reflect the last time I made any changes to it. Conversely, if the date on the document is old, it means that the automatic update failed: please let me know if this happens. Note (July 2021): the above notes have been revised extensively. The older version is here.
