The class starts with a brief (about a week long) excursion into basic facts concerning Ordinary Differential Equations. It will not dwell on solving special types of equations, which you all have seen in an undergraduate ODE class. I will rather concentrate on several major theorems, which are usually not treated well in the undergraduate classes: solutions' existence, uniqueness, and dependence on parameters. We'll also see that all these theorems are consequences of a single geometric one, on straightening a vector field. We'll also discuss how to tell whether an applied problem in hand can be modeled by a (system of) ODE. Surprisingly, one can get an answer to this question.

We will shift then to the Partial Differential Equations, probably one of the most active, diverse, and beautiful areas of pure and applied mathematics. Besides numerous applications inside mathematics (e.g., to geometry, several complex variables), the PDEs form the core part of our scientific understanding of the physical world: from physics to chemistry, to biology, to medical diagnostics, to meteorology, you name it.

The class (except the short initial ODE part) will be based on the well respected textbook by L. Evans. It is planned to cover Part I "Representation formulas for solutions" of the book. This includes a study of the four major PDEs: transport, Laplace, heat, and wave equations, as well as analysis of 1st order non-linear PDEs and other methods of representing solutions (Fourier transform, separation of variables, asymptotics, etc.). Knowing these equations well is a prerequisite for deeper understanding of more general PDEs.

This study will be continued in the next class Math 612 that will most probably cover the Part II of the book "Theory of linear PDEs" (including more general initial value and boundary value elliptic, hyperbolic, and parabolic problems, spectral theory, etc.).

Prerequisite: MATH 410 or equivalent or instructor's approval.

Grading will be based on home assignments and a take-home final exam.

General remarks about writing:
  1. Write solutions neatly and not in microscopic letters. Avoid many crossing outs, etc. This is not only for me to read easier, but for you to be sure that what you write is correct. I will not grade solutions that are messily written and unreadable due to a tiny letter size.
  2. Avoid words ``trivial ..., easy to see ..., obvious ...'' and other their synonyms. ``Easy to see'' or ``trivial'' should mean that you can show this in a second, so just do it :-). By the way, errors are usually appearing in ``obvious'' places.
  3. Be careful with parentheses and other such standard rules; they can cause mistakes if not followed properly.
  4. Make sure you understand your own logic completely. If you don't, I won't. :-)

    Recommended reading: All of the books below are written by great experts in differential equations, all are written well and provide interesting and rewarding reading. This list is certainly far from being comprehensive, it just contains some of the instructor's favorites. These books approach the subject from different perspectives, and so reading (or at least browsing through) all of them is a good idea for someone who wants to learn the ODEs and PDEs. Do not try to do this in one semester, though :-).

    Make-ups for missed quizzes, home assignments and exams will only be allowed for a university approved excuse in writing. Wherever possible, students should inform the instructor before an exam or quiz is missed. Consistent with the University Student Rules: students are required to notify an instructor by the end of the next working day after missing an exam or quiz. Otherwise, they forfeit their rights to a make-up.
    Grade complaints: Sometimes the instructor might make a mistake grading your work. If you feel that this has happened, you have one week since the graded work was handed back to you to talk to the instructor. If a mistake is confirmed, the grade will be changed. No complaints after that deadline will be considered.

    Copying work done by others, either in-class or out of class, is an act of scholastic dishonesty and will be prosecuted to the full extent allowed by University policy. Collaboration on assignments, either in-class or out-of-class, is forbidden unless permission to do so is granted by your instructor. For more information on university policies regarding scholastic dishonesty, see University Student Rules
