Prerequisite
Description
This course is designed to provide students with a rigorous treatment of the theory of differential equations.
Desired Learning Outcomes
This course is aimed at graduate students in Mathematics as well as graduate students in Physics and Engineering. This course contributes to all the expected learning outcomes of the Mathematics M.S. and Ph.D. The topics include the existence, uniqueness, and continuation of solutions to differential equations, linear differential equations, and stability of solutions for differential equations.
Prerequisites
Students should have taken Math 316 and Math 334 prior to taking this course. Math 316 provides a rigorous background of analysis that is needed to understand many of the proofs in this course. Math 334 provides the students an understanding of basic properties of differential equations and techniques used to solve differential equations.
