The notes below are written in a concise form that is less readable than a textbook. They may be useful as condensed summaries but are not meant to be a replacement for a more complete explanation.
Some of the notes were written as part of course material. As such they are not written in full generality and sometimes are not completely accurate. For example, measure-theoretic arguments are omitted and some assumptions such as differentiability are implicitly made.
Please notify me if you find any mistakes or typos.
