Complex Patterns in a Simple System
1 Center for Nonlinear Studies, Los Alamos National Laboratory, Los Alamos, NM 87545
Numerical simulations of a simple reaction-diffusion model reveal a surprising variety of irregular spatiotemporal patterns. These patterns arise in response to finite-amplitude perturbations. Some of them resemble the steady irregular patterns recently observed in thin gel reactor experiments. Others consist of spots that grow until they reach a critical size, at which time they divide in two. If in some region the spots become overcrowded, all of the spots in that region decay into the uniform background. Submitted on April 7, 1993Accepted on May 13, 1993
