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