Destabilization of localized structures induced by delayed feedback — •Svetlana Gurevich and Rudolf Friedrich — Institut for Theoretical Physics, University of Münster, Wilhelm-Klemm-Str. 9, D-48149
We study the properties of one- and two-dimensional localized structures in reaction-diffusion systems and in the Swift-Hohenberg equation subjected to a delayed feedback. We compare the spectral properties of both models and show that for reaction-diffusion systems the delay can induce complex behavior of the localized structures, including, e.g., spontaneous motion and breathing of the objects.
