11 Dec 2000 | | Journal: | Physical Review E 64, 036205 (2001) | | Subject: | Chaotic Dynamics; Pattern Formation and Solitons | nlin.CD nlin.PS | | Affiliation: | 1,2), Emilio Hernandez-Garcia and Oreste Piro ( CATS, Copenhagen, Denmark; IMEDEA, Palma de Mallorca, Spain | | Abstract: | We investigate the influence of walls and corners (with Dirichlet and Neumann boundary conditions) in the evolution of twodimensional autooscillating fields described by the complex Ginzburg-Landau equation. Analytical solutions are found, and arguments provided, to show that Dirichlet walls introduce strong selection mechanisms for the wave pattern. Corners between walls provide additional synchronization mechanisms and associated selection criteria. The numerical results fit well with the theoretical predictions in the parameter range studied. | | Source: | arXiv, nlin.CD/0012024 | | Services: | Forum | Review | PDF | Favorites | |
