Wavebumber selection and persistent dynamics in models of convection
The wavenumber selected in nonlinear spatially periodic states of driven systems is systematically investigated using analytic and numerical techniques on equations modeling convection. Different selection mechanisms yield different results, arguing against the existence of a general minimizing principle. Two incompatible selection mechanisms operating together lead to a persistently dynamic state. © 1986.
