Workshop : Complex Dynamics of Networks of Oscillators : From Basic Research to Novel Therapy

Contents

Program

Dates:
November 4-6, 2005
Venue:
Room 508 (5th floor), Building #4, Department of Mathematics, Hokkaido University
Organizers:
Yoshiki Kuramoto (Hokkaido Univ.), Peter Tass (Research Center Juelich)
Objective:
In recent years, the study of coupled oscillators is becoming relevant to wider and wider areas of scientific disciplines centered around life sciences. While the theory of coupled oscillators which has been established over the last decades is now finding many new applications, predicting new phenomena yet unobserved and further generalization and refinement of its theoretical basis also form equally important research themes.
This workshop will be held officially as a scientific event under the heading "German-Japanese Year", and its organization is partially supported by the German government. We expect a few tens participants mostly from Germany and Japan. The major part of the German participants and a small number of Japanese participants are from the field of therapeutic applications of oscillator networks, still the workshop as a whole is intended to cover much wider topics which include modeling and analysis of synchronous activities in living systems in general and also revisiting fundamental aspects of the theory of coupled oscillators. We encourage everyone concerned to join us.
Participation Fee: Free
