Warning: My Youtube Channel was removed on June 16, 2025.
All links to videos and playlists in my courses fail without it.
I am working on the appeal process and hopefully it will return.
Below is my usual website with many failed links.
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. See below:
Linear Algebra, MAT313, Lehman College
Differential Geometry, MAT432, Lehman College
Analysis I, MAT320/MAT640, Lehman College
Vector Calculus, MAT226, Lehman College
Axiomatic Geometry, MAT345, Lehman College
Algebra and Number Systems, MAT314, Lehman College
I taught these courses at Lehman College of the City University of New York.
