Andrew D. Lewis's Courses Notes

Having taught a few courses over the years, and some of these courses many times, I have been able to write some relatively comprehensive course notes. I put these here for public consumption, but make caveats:
  1. These are almost all incomplete, although some parts of some collections of notes are quite complete. But, no matter how complete something seems, it is offered without warranty, explicit or implied.
  2. If you wish to use these notes for a course, you are welcome to do so. I would ask, however, that you let me know, just as a courtesy.
