Swift-Hohenberg方程拟模式解的存在性

On the existence of quasipattern solutions of the Swift-Hohenberg equation

G. Iooss, A. M. Rucklidge

摘要:

准图案(在任何空间方向上都是准周期性的二维图案)仍然是斑图形成的突出问题之一。与涉及准周期性的问题一样,有一个小除数问题。本文考虑Swift-Hohenberg方程的8重、10重、12重和高阶拟模式解。我们证明了一个正式的解决方案,给出了一个发散的系列,可以用来建立一个光滑的准周期函数,这是一个近似的解决方案的图案形成偏微分方程的指数小的错误。

英文摘要:

Quasipatterns (two-dimensional patterns that are quasiperiodic in any spatial direction) remain one of the outstanding problems of pattern formation. As with problems involving quasiperiodicity, there is a small divisor problem. In this paper, we consider 8-fold, 10-fold, 12-fold, and higher order quasipattern solutions of the Swift-Hohenberg equation. We prove that a formal solution, given by a divergent series, may be used to build a smooth quasiperiodic function which is an approximate solution of the pattern-forming PDE up to an exponentially small error.
