Abstract
We consider the evolution of hexagonal convection patterns governed by non-potential amplitude equations in the particular case of the Bouss inesq approximation. The amplitude equations contain new terms which c an produce non-equilateral hexagonal patterns based on a resonant tria d with different lengths of wave vectors. The stability regions of dif ferent kinds of patterns have been obtained. Non-stationary solutions are also studied. (C) 1998 Elsevier Science B.V. All rights reserved.
