The lecture notes on this page (see below) cover all or parts of classes I taught where these notes were either handed out to students as supplementary reading material or simply made for my own convenience when teaching a paper. They have, however, been edited to add ample exposition since the original talk notes were largely just equations after equations. Some may be updated/improved over time while others may only be a first draft; the latest versions of these notes will be available on this page for anyone interested in using them for either reference or learning.

You may notice that older notes have been laid out differently. Newer ones use my LaTeX `lecture`

class and have a more consistent tone. The `lecture`

class is available for free on Github if you wish to use it yourself; if you wish to help develop it, please feel free to fork it or just send me an e-mail with your suggestions. (Read more further down this page.)

**2020 Update.**A new Github repo has been opened, with several of these notes and their source files, where you can contribute directly by making changes and quickly submitting a pull request.
