"Suppression of anomalous diffusion in even dimensions"


Abstract:

It is known that weakly chaotic dynamics, such as the type generated by 
Pomeau-Manneville intermittency maps, may lead to anomalous diffusion 
(Levy processes).  I will describe work in progress with Georg Gottwald 
indicating that when analysed in the context of systems with Euclidean 
E(n) symmetry, typically the anomalous diffusion persists if and only if 
n is odd.
In even dimensions, the anomalous diffusion is typically suppressed and 
replaced by Brownian motion.
