ORDINARY DIFFERENTIAL EQUATIONS I22M:214
SPRING SEMESTER 2010
This course is a continuation of 22M:213 (Ordinary Differential
Equations I). Though the course is mostly about the theory of ordinary
differential equations (ODEs), we may consider this
theory in conjunction with some theoretical and practical
aspects of numerical methods for ODEs.
If you have a high interest in a specific topic related to ODEs,
please let me know. If a majority of students taking the class
is interested in the topic then I may cover it.
