Scaling and Selection in Cellular Structures and Living Polymers

Abstract

The dynamical behavior of two types of non-equilibrium systems is discussed: $(a)$ two-dimensional cellular structures, and $(b)$ living polymers. Simple models governing their evolution are introduced and steady state distributions (cell side in the case of cellular structures and length in the case of living polymers) are calculated. In both cases the models possess a one parameter family of steady state distributions. Selection mechanism by which a particular distribution is dynamically selected is discussed.
