Bifurcation Analysis of the 1d and 2d Generalized Swift–hohenberg Equation

Abstract: In this paper, bifurcation of the generalized Swift-Hohenberg equation is considered. We first study the bifurcation of the generalized Swift-Hohenberg equation in one spatial dimension with three kinds of boundary conditions. With the help of Liapunov-Schmidt reduction, the original equation is transformed to the reduced system, and then the bifurcation analysis is carried out. Secondly, bifurcation of the generalized Swift-Hohenberg equation in two spatial dimensions with periodic boundary conditions is also… Show more

“…Compared with our previous work [18], in which β|∇u| 2 in (1.3) is replaced by βu 2 , in the case (n, m) = (k, k), the type of the bifurcation points and the stability of the four bifurcated solutions don't change, despite γ (0) and the eigenvalue λ(ε) of the linearized eigenvalue problem around the nontrivial solutions are different from the ones in [18].…”

“…In our previous work [18], we consider the bifurcation of the two-dimensional generalized Swift-Hohenberg equation In [19], the existence of a global attractor is proven for the modified Swift-Hohenberg equation which reads ∂u ∂t = αu − (1 + ∆) 2 u + β|∇u| 2 − u 3 , (1.2) near the onset of instability with the Dirichlet's boundary condition and periodic boundary condition, where α is a bifurcation parameter, and β is a constant. The term β|∇u| 2 reminds us of the Kuramoto-Sivashinsky equation, introduced by Kuramoto [20] as a model describing phase turbulence in reaction-diffusion systems and by Sivashinsky [21] for the study of flame propagation.…”

“…As in the case of the MSHE, it is known from [4,8,11,20] that under the condition (1.4) and the periodic condition, the SHE and the GSHE bifurcate from the trivial states to S 1 -attractorsà N (α) and N (α), respectively. However, there are big differences in the structures of A N (α),à N (α), and N (α).…”
