摘要：

We study the stability of breathers in the damped sine-Gordon system driven by an external ac force in the case when the amplitude of the driving field is spatially inhomogeneous. Physical applications are e.g. an ac-driven long Josephson junction and ac-driven magnetic solitons. We consider analytically the conditions for the stability of the driven breather against phase and position disturbances. The results are illustrated by numerical simulations.
