Unfortunately I have been told that I may no longer be able to modify the information on my decades old page. You can go there for now (hopefully it will always be accessible, just unsure if I can modify) for old courses, papers, talks. I am hoping that eventually I will be able to migrate and post information as accessibly here, but for now for old stuff go to https://web.williams.edu/Mathematics/sjmiller/public_html/ and for the more current classes click on the page links here.
