Welcome to the course website for Differential Equations and Applications . This course is an introduction to the subject of differential equations which arises in many branches of mathematics and in applications. This class aims to cover both core theoretical topics as well as practical aspects for how to analyze and solve differential equations. More information can be found in the syllabus below and on the course website. I look forward to working with you this quarter.
