DCDS

Cellular networks are ubiquitous in nature. They exhibit behavior on many different length and time scales and are generally metastable. Most technologically useful materials are
polycrystalline microstructures composed of a myriad of small
monocrystalline grains separated by grain boundaries. The
energetics and connectivity of the grain boundary network plays a
crucial role in determining the properties of a material across a wide
range of scales. A central problem in materials science is to
develop technologies capable of producing an arrangement of
grains—a texture—appropriate for a desired set of material
properties. Here we discuss the role of energy in texture development, measured by a character distribution. We derive an entropy based theory based on mass transport and a Kantorovich-Rubinstein-Wasserstein metric to suggest that, to first approximation, this distribution behaves like the solution to a Fokker-Planck Equation.

DCDS

Recently, several numerical invariants have been introduced to characterize
the distortion induced by automorphisms of a free group.
We unify these by interpreting them in terms of an entropy function
of a kind familiar in thermodynamic ergodic theory. We draw an analogy
between this approach and the Manhattan curve associated to a
pair of hyperbolic surfaces.
