Towards the Understanding of Complex Dynamics in Dissipative Systems

10:00 AM-12:00 PM
Koali (Salon 5)

Pattern formation theory has been focused on finding characteristic objects such as traveling pulse and spiral waves. One recent trend is to study the interaction among them, especially, pulse interaction, like repulsion or attraction. This is due to the fact that pulses don't lose their identities and interact weakly through tails. On the other hand, annihilation of waves or self-replication dynamics is a typical example of strong interaction and they are important building blocks for complicated pattern dynamics. The speakers will provide an overview along this direction and illustrate relevancy to real biological/chemical problems.
