The Dynamics of Curved Fronts: Beyond Geometry

patt-sol 2009-10-30 v1 Pattern Formation and Solitons

Abstract

We derive a new set of kinematic equations for front motion in two-dimensional bistable media. The equations generalize the geometric approach by complementing the equation for the front curvature with an order parameter equation associated with a nonequilibrium Ising-Bloch bifurcation. The resulting equations capture the core structure of spiral waves and spontaneous spiral-wave nucleation.
