Wael Bahsoun (University of Loughborough): Map lattices coupled by collisions: chaos per lattice unit.

BudWiSer - The Budapest - Wien Dynamics Seminar 

Abstract: 
We study coupled map lattices where the interaction takes place via rare but intense 'collisions' and the dynamics on each site is given by a piecewise uniformly expanding map of the interval. Using transfer operator techniques, we derive an explicit formula for 'first collision rates' per lattice unit. This is joint work with F. Selley.
