Coherent Structures Generated by Inhomogeneities in Oscillatory Media
We investigate the effect of spatially localized inhomogeneities on a spatially homogeneous oscillation in a reaction-diffusion system. In dimension up to 2, we find sources and contact defects, that is, the inhomogeneity may either send out phase waves or act as a weak sink. We show that small inhomogeneities cannot act as sources in more than 2 space dimensions. We also derive asymptotics for...
متن کاملEpicyclic drifting in anisotropic excitable media with multiple inhomogeneities
Spirals have been studied from a dynamical system perspective starting with Barkley’s seminal papers linking a wide class of spiral wave dynamics to the Euclidean symmetry of the excitable media in which they are observed. However, in order to explain certain nonEuclidean phenomena, such as anchoring and epicyclic drifting, LeBlanc andWulff introduced a single translational symmetry-breaking pe...
متن کاملScalar and Tensor Inhomogeneities from Dimensional Decoupling1
We discuss some perturbative techniques suitable for the gauge-invariant treatment of the scalar and tensor inhomogeneities of an anisotropic and homogeneous background geometry whose spatial section naturally decomposes into the direct product of two maximally symmetric Eucledian manifolds, describing a general situation of dimensional decoupling in which d external dimensions evolve (in confo...
متن کاملNoise-induced excitability in oscillatory media.
A noise-induced phase transition to excitability is reported in oscillatory media with FitzHugh-Nagumo dynamics. This transition takes place via a noise-induced stabilization of a deterministically unstable fixed point of the local dynamics, while the overall phase-space structure of the system is maintained. Spatial coupling is required to prevent oscillations through suppression of fluctuatio...
متن کاملDefects in Oscillatory Media: Toward a Classification
We investigate, in a systematic fashion, coherent structures, or defects, which serve as interfaces between wave trains with possibly different wavenumbers in reaction-diffusion systems. We propose a classification of defects into four different defect classes which have all been observed experimentally. The characteristic distinguishing these classes is the sign of the group velocities of the ...
