The full amplitude equation (as introduced by Newell and Whitehead and Segel) is derived directly from the hydrodynamic equations for both "free" and "rigid" upper and lower boundaries. ... The coefficients involved, including the interaction parameter of nonparallel rolls, are explicitly calculated for ... Item Type: Article...

An amplitude equation is derived for a four-wave-mixing geometry with nearly counterpropagating, mutually incoherent, nondiffracting pump beams, spatially overlapping in a photorefractive material with a nonlocal response. ... This equation extends the earlier linear two-dimensional theory to the weakly nonlinear regime.

Based on the method of multiple scales we derive a system of coupled amplitude equations for the slowly varying part of the longitudinal distribution function and for the resonator wave envelope, The equation governing the slow evolution of the voltage envelope is shown to be of Ginzburg-Landau type.
