Dependence of Initial Value on Pattern Formation for a Logistic Coupled Map Lattice
The logistic coupled map lattices (LCML) have been widely investigated as well as their pattern dynamics. The patterns formation may depend on not only fluctuations of system parameters, but variation of the initial conditions. However, the mathematical discussion is quite few for the effect of initial values so far. The present paper is concerned with the pattern formation for a two-dimensiona...
متن کاملPattern formation in diffusive-advective coupled map lattices.
We investigate pattern formation and evolution in coupled map lattices when advection is incorporated, in addition to the usual diffusive term. All patterns may be suitably grouped into five classes: three periodic, supporting static patterns and traveling waves, and two nonperiodic. Relative frequencies are determined as a function of all model parameters: diffusion, advection, local nonlinear...
متن کاملOn Circle Map Coupled Map Lattice
The circle map in one and two dimensions is studied. Both its stability and synchronization , using a bounded control and persistence, are discussed. This work is expected to be applicable in ecology where spatial effects are known to be important. Also, it will be relevant to systems where delay effects are not negligible.
متن کاملIteration of the coupled map lattice construction
We define a class 3 of topological dynamical systems, which are left invariant by coupled map lattice constructions. ‘fhis class .F has the property that if the coupling of the systems is sufficiently weak and (M, f) contains a hyperbolic set, ‘hen the new system $( M, f) obtained by the coupled map lattice construction has a hyperbolic set too. The coupled map attice construction, map 4, can b...
متن کاملLocalization in a Coupled Standard Map Lattice
We study spatially localized excitations in a lattice of coupled standard maps. Time-periodic solutions (breathers) exist in a range of coupling that is shown to shrink as the period grows to innnity, thus excluding the possibility of time-quasiperiodic breathers. The evolution of initially localized chaotic and quasiperiodic states in a lattice is studied numerically. Chaos is demonstrated to ...
