MAT 391E - Advanced Topics in ODE

Course Objectives

1. Teach the basics on stability of dynamical systems.
2. To develop a basic understanding of occurrence of two point boundary value problems, their classification and related problems; such as, initial value, boundary value and initial-boundary value problems in the real world.
3. To develop a basic understanding of the theory and methods of solutions for these problems.
