This blog is essentially created as a companion to the course **Analytic and Geometric Theory of Ordinary Differential Equations**, to be served at the Weizmann Institute in 2007/8 academic year. Here are a few questions that are usually asked at the beginning.

- The course is covered by the textbook “Lectures on Analytic Differential Equations” by Ilyashenko and Yakovenko (to arrive at the WIS library shortly). In the meantime the draft version (full of errors and typos) is available.
- The course will end up with an exam. The exam is take-home, about 10 problems for a couple of weeks.
- Pre-requisites: basic proficiency in the language of geometry (manifolds, vector fields, differential forms) and functions of (one) complex variable won’t harm, though I will try to make this course as self-consistent as possible. A primitive First Aid is available on functions of several variables and Riemann surfaces. An extensive treatment can be found in the W. Ebeling’s book (highly recommended).
- There will be no home assignments, however, it is highly advised to look at the Problems and Exercises sections of the textbook, at least for self-control. Questions (and answers) are most welcome on the pages of this blog.

See you on **Thursdays at Zyskind Building, Lecture Room 1, between 9:00 and 11:00**.

**P.S.**This hosting (WordPress) allows for easy insertion of LaTeX code, which makes mathematical discussions here especially pleasant: e.g., one of the main heroes of the course will be the equation

**P.P.S.** For your convenience: (updated) Table of Contents and Introduction, Bibliography and Index.

### Blogging rules.

For those not familiar with the blogging subculture (are there such people?): you are welcome to leave your comments/questions/remarks next to the relevant posts. Please introduce yourself when commenting. My wet dream is mathematical discussions between the students attending the course on these pages. Don’t be afraid to express yourself and teach others. I promise not to abuse my rights as a moderator here.

Any language is accepted, though I **strongly** urge to write in the l.c.d. (= Simple English).
