A1 - Pikovskij, Arkadij T1 - Localisation in a coupled standard map lattice N2 - 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 infinity, 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 spread Y1 - 1998 UR - http://www.stat.physik.uni-potsdam.de/~markus/papers/PhD119-4.ps.gz ER - TY - JOUR A1 - Abel, Markus A1 - Flach, S.

T1 - Nonlinear localization periodic solutions in a coupled map lattice N2 - We prove the existence of nonlinear localized time-periodic solutions in a chain of symplectic mappings with nearest neighbour coupling. This is a class of systems whose behaviour can be seen as representation of a lattice of pendula. The effect of discrete time changes the mathematical as well as the numerical procedures. Applying the discrete version of Floquet theory eases and clarifies the procedure of proving the existence of the localized time-periodic solutions. As an extension of the concept of rotobreathers one can produce solutions which rotate at every site of the lattice. To consider these we use a general definition of localization.
