## Technical Notes

- 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.
