Topological Solitons/Numerical Analysis Seminar: Some Comments on non Integrable Systems

Presented by Bernard Piette, Durham

14 March 2007 14:15 in CM221

In my talk I will talk about some of the differences between integrable
and non-integrable systems. In particular, I will show that vibration modes
play a key role in the dynamic of non-integrable system.

The examples I will look at are the 2 dimensional New Baby Skyrme Model and
the sine-Gordon model with a potential well. Amongst other phenomena, I will
show how the breaking of the integrability of the sine-Gordon model allows
one to split breathers into a kink anti-kink pair
