Spatio-temporal chaos for the Gray–Scott model

Y Nishiura, D Ueyama - Physica D: Nonlinear Phenomena, 2001 - Elsevier
A new geometrical criterion for the transition to spatio-temporal chaos (STC) arising in the
Gray–Scott model is presented. This is based on the inter-relationship of global bifurcating …
