Hj. Zhao et Sq. Tang, Nonlinear stability and optimal decay rate for a multidimensional generalized Kuramoto-Sivashinsky system, J MATH ANAL, 246(2), 2000, pp. 423-445
We study the Cauchy problem for a generalized Kuramoto-Sivashinsky system i
n multidimension. The zero equilibrium is linearly stable for coefficients
within a certain range. We further establish the global existence, nonlinea
r stability, and optimal decay rate of the solution for coefficients within
the same range, though with suitable restriction to the initial data. (C)
