摘要
<Abstract>The periodic windows in weakly coupled map lattices with both diffusive and gradient couplings are studied. By using the mode analysis method,which reduces the behavior of the coupled systems to a few numbers of independent modes,we theoretically analyze the detailed structures of the periodic windows.We find that the gradient coupling greatly enlarges the width of the periodic windows,compared with the diffusive coupling.
The periodic windows in weakly coupled map lattices with both diffusive and gradient couplings are studied. By using the mode analysis method, which reduces the behavior of the coupled systems to a few numbers of independent modes, we theoretically analyze the detailed structures of the periodic windows. We find that the gradient coupling greatly enlarges the width of the periodic windows, compared with the diffusive coupling.
