Asynchronous Online Courses that I taught in 2020-2024 covering most advanced courses in a Mathematics Major:
These courses were taught asynchronously online with prerecorded video lectures as playlists on youtube, classwork with video solutions, and homework/quizzes. These are free for anyone to use if they wish to learn a course on their own or supplement their knowledge by looking over a specific topic within a lesson of one of the courses. All the courses may be viewed by prior students or fellow faculty.
Sadly my Youtube Channel was removed in June 2025 (so none of the linked playlists of the videos that I created for these courses work any longer) but the notes are still there. I never backed up my youtube channel and so all was lost.
