Undergraduate Workshop

Aug 9-14 2010

University of Texas at Austin

INTRODUCTION TO THE STUDY OF LONG-TERM BEHAVIOR OF NONLINEAR SYSTEMS

SUMMARY:

Many systems in nature have non-linear laws of evolution. It can happen that even simple laws of evolution can lead to a very complicated evolution. The goal of the workshop is to present some analytical and numerical methods that can lead to understanding of these phenomena.

PREREQUISITES:

A standard undergraduate course in differential equations and some ability to use computers. It will also be desirable to have some more mathematical maturity, such as a course in linear algebra or a course in real analyisis or topology.

STRUCTURE:

There will be 4 daily hours of lectures by Profs. M. Capinski, and R. de la Llave and graduate assistants. The lectures will be supplemented by practices based on XPPAUT, OCTAVE (Feel free to download them in your computers).

SUPPORT:

There will be financial support for students to attend the course.

Students from U. Texas at Austin will receive an stipend. Students from outside Austin will receive lodging and a meal allowance.

Unfortunately, the period to apply to attend the worshop and to request finacial support expired June 20 2010

U.T. Austin Students should be aware that there are also fellowships for further study associated with the RTG grants. Information about this opportunity including application forms are here

All the above support opportunities are subject to citizenship/residency requirements.
