One-time change of schedule

Filed under: lecture,schedule — Sergei Yakovenko @ 3:31

Because of the travel arrangements, the next lecture on “Analysis for high school teachers” is moved from Tue Nov 17, 9:15-11:15 (Sci teaching lab) to Thu Nov 19, 9:15-11:15 (Seminar room 2).
For the same reasons the next course by Dmitry Novikov is moved from Thu Nov 19, 9:15-11:15 (Seminar room 2) to Tue Nov 17, 9:15-11:15 (Sci teaching lab).

In other words, the two classes will simply swap their space-time slots for one week only.

Carissimi!

This post is to announce the midi-course (about 24 hours) that will be given in November-December in Universita di Pisa. The weekly timetable is as follows,

Lunedi 11-13 Aula 1
Venerdi 9-11 Aula 1.

The course will be based (among other) on severalย principalย sources, all available online. Here are the links:

  1. Yu. Ilyashenko, S. Yakovenko, Lectures on analytic differential equations, MR2085816 (2005f:34255). Mainly Chapter III and Section 26.
  2. D. Novikov, S. Yakovenko, Lectures on meromorphic flat connections, In: Normal forms, bifurcations and finiteness problems in differential equations, 387–430, NATO Sci. Ser. II Math. Phys. Chem., 137, Kluwer Acad. Publ., Dordrecht, 2004 (Preprint math.CA/0212334).
  3. Yakovenko, S. Quantitative theory of ordinary differential equations and tangential Hilbert 16th problem, Preprint math.DS/0104140 (2001). On finiteness in differential equations and Diophantine geometry, CRM Monogr. Ser., vol. 24, Amer. Math. Soc., Providence, RI, 2005, pp. 41โ€“109, MR2180125 (2006g:34062)

Take-home exam

The last effort

Here you can find the problems for the take-home exam. The rules of the game are outlined in the preamble, I copy them here for your convenience.

The following problems are suggested for the home exam, to be submitted no later than by March 8, 2012. Almost each problem consists of several subproblems, arranged in a specific order. This order is not accidental and should be considered as an implicit hint: solutions of subsequent problems are based on the preceding ones. Please take care to avoid the words “obvious”, “clearly” etc., use as few “plain” words as possible and instead write the intermediate assertions in a closed and precise form using the quantifiers and standard set theoretic notations.

The problems have different complexity: some are easier, some require additional ideas, but none of them is “computational”: if your solutions involves too many identical transformations and/or other computations, have a second look, whether you indeed answer the question that was asked, or something different.

To get the full score 100, it is not necessary to solve all problems and answer all questions: the grade will be awarded based on your demonstrated understanding of mathematics and not on your familiarity with some theorems.

Don’t forget to consult the lecture notes: sometimes you may find useful hints or examples there.

For your convenience Dima will soon post the Hebrew translation of these problems.

Don’t hesitate to ask questions in the comment field: we’ll try to answer them to the extent permissible for an independent home assignment ๐Ÿ˜‰

Good luck!

UPD (Feb 06, 2012, 8:30 am) A small correction of Problem 9 made (sign corrected + more accurate wording).
