Here is the most recent version of the notes (September 8, 2024): pdf version.
Here is an html version. (I thank Wanmin Liu for creating this version.)
When referring to anything in the notes please mention the date (i.e., the version). Also, it far is better to refer to the section/exercise/etc. rather than the page number since this is what will be most consistent over versions.
Discussion on the evolving notes are here.
Here are older versions of the notes, which should be considered outdated, but are kept available because previous discussion may refer to them.
