Course materials

• The syllabus for the Spring 2026 course is available here.
• My old handwritten notes for ordinary differential equations, which I taught at Brown University in Summer 2019, are available here. The lectures will loosely follow these notes, with modifications here and there. Use at your own risk. If you are a lecturer or professor and wish to use my notes for your course, please email me (see contact information on my main page) to let me know and give due credit.
