Abstract
A Swift-Hohenberg model incorporating a nonlinear resonance is shown t o produce stable rolls only in a closed region of the parameter space. This Busse balloon is limited by zigzag and Eckhaus boundaries. A ske w-varicose instability outside the balloon also exists. Implications w ith nonlinear optics and hydrodynamic convection are commented. (C) 19 98 Elsevier Science B.V.
