ORDINARY DIFFERENTIAL EQUATIONS I22M:213
FALL SEMESTER 2009
Course announcement.
This course is a natural continuation of 22M:142 (nonlinear
dynamics with numerical methods).
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 during
Spring semester 2010.

RECOMMENDED READINGS FROM THE TEXTBOOKS (AND FROM OTHER REFERENCES)
 In Gelfand: 1.11.4, 1.7 on variational Calculus and the first variation
 In Arnold: 12 on variational Calculus
 In Gelfand: 5.245.28 on the second variation
 In Gelfand: 2.9 and 5.29 on generalization to n unknown functions
 In Arnold: Part I (Chapters 1 and 2) on Newtonian mechanics (as light reading)
 In Arnold: 13, 17, 19, and 21 on Lagrangian mechanics and variational principles
 In Gelfand: 4.21 on Hamilton's principle
 In Arnold: 14 and 15 on Hamiltonian systems
 In Gelfand: 4.164.18 on the Hamiltonian formulation of EulerLagrange equations
 In Arnold: Chapter 7 (3236) on differential forms
 In Arnold: 37, 38, and 44 (D from p.238E) on symplectic structure and Hamiltonian systems.
Warning: 'symplectic transformation' in Arnold are called 'canonical transformation'
which may be a source of confusion since 'canonical transformations'
in the literature are defined differently and are (slightly) more
general than symplectic transformations
 In Arnold: 20 on Noether's Theorem
 In Gelfand: 4.20 on Noether's Theorem and 4.22 on some first integrals
 In Arnold: 16 on volume preservation and the Poincare recurrence Theorem
 In Arnold: 44 on the PoincareCartan integral invariant

"Public health authorities have recommended that people with flulike illnesses stay home and not return to public spaces until 24 hours after
they have no fever. In order to prevent the spread of disease, please do not come to class, meet with other groups of students, attend office
hours, or contact offices in person while you are ill. Based on this recommendation, I will not require you to report to a doctor or to Student
Health to verify a flulike illness if you are ill, please complete
an illnessabsence form
when you are well enough to do so.
Your grade will not be penalized for absences if you are following the recommendations of health authorities."
