Email, Office Hours, and Grades

The office hours are intended to be used to help students with questions about mathematical problems. They can also be used to discuss exam scores and a student's progress in the course. Email will not be used for these purposes. As a standard policy, no grades or exam scores will be sent out to students via email or over the phone.

Catalog Description

Math 557. Ordinary Differential Equations and Dynamical Systems. (3-0) Cr. 3. F. Prereq: 415 or 501. The initial-value problem, existence and uniqueness theorems, continuous dependence on parameters, linear systems, stability and asymptotic behavior of solutions, linearization, dynamical systems, bifurcations, and chaotic behavior.


Ordinary Differential Equations and Dynamical Systems , by Gerald Teschl .

Course Policies

This is a graduate course that develops the theory of ordinary differential equations. Students will learn the theoretical foundations of the cornerstone topics of the subject that are listed in the catalog description above. Applications to specific problems will be discussed so that students will be able to apply their knowledge of the subject to problems they encounter as they continue their studies and start to conduct mathematical research. The assessments of student learning will be mainly in the form of homework assignments that will be posted below. At the discretion of the instructor there could be announced exams. Students can discussed the problems in the homework assignments with classmates, but should submit solutions to the problems that are written up as their own independently prepared work. Homework assignments will be given explicit due dates. In the event that a student is unable to turn in an assignment by the due date, the student should discuss the circumstances of the event with the instructor.

Grading Policy

Course grades will be determined from student performance on homework assignments and possibly one or two exams that would correspond to a midterm and/or final exam. There will be four to six homework assignments, and at most two exams.

Disability Resources

Iowa State University complies with the American with Disabilities Act and Section 504 of the Rehabilitation Act. If you have a disability and require accommodations, please contact the instructor early in the semester so that your learning needs may be appropriately met.
