Fingerprint Dive into the research topics of 'Instability of radially-symmetric spikes in systems with a conserved quantity'. Together they form a unique fingerprint. Together they form a unique fingerprint. Spatially periodic, temporally stationary patterns that emerge from instability of a homogeneous steady state were proposed by Alan Turing in as a mechanism for morphogenesis in living systems and have attracted increasing attention in biology, chemistry, and physics. Patterns found to date have been confined to one or two spatial dimensions. We used tomography to study the .

Allee eﬀect f(u) = au µ n K0 −1 ³ 1− n K ´ The basis of this model approach is still the logistic growth, but if the population is too low, it will also.

Background. Turing models and general reaction–diffusion systems have been used to study mechanisms leading to emergent spatial patterns. Such studies have proved useful in a wide range of fields, including Biology, Chemistry, Physics, Ecology and Economics (see [] and references therein).Patterns arising in reaction–diffusion processes can be observed in well-known oscillatory .

Employing the bifurcation theory and the comparison principle, we investigate the nodal property of positive stationary solution along the bifurcating branches, and establish the representation of bifurcating branch.

In this paper, we present computational techniques to investigate the effect of surface geometry on biological pattern formation. In particular, we study two-component, nonlinear reaction–diffusion (RD) systems on arbitrary surfaces.

We build on standard techniques for linear and nonlinear analysis of RD systems and extend them to operate on large-scale meshes for arbitrary. Radially symmetric patterns are observed in pin-to-plane DC plasma systems where a liquid solution is used as a planar resistive anode.

The size and structure of these patterns depends on the plasma current and salt concentration of the liquid anode. Book January Radially Symmetric Patterns of Reaction-Diffusion Systems Contents 1 Introduction 3 2 Instabilities of Reaction-Diffusion Systems in One Spatial Dimension 11 In this paper, we consider a reaction-diffusion system which describes the dynamics of population density for a two competing species community, and discuss the structure on the set of radially symmetric positive stationary solutions for the system by assuming the habitat of the community to be a.

The mathematical model of reaction–diffusion provides a framework for designing and engineering programmable structures through chemical computing. 6–9 In this model, spatial patterns can emerge from local interactions between diffusing agents.

Next we show how to infer from it a lack of blowup of radially symmetric solutions to a Keller-Segel system in $\Omega$. We performed an extensive numerical study of pattern formation scenarios in the two-dimensional Gray-Scott reaction-diffusion model.

We concentrated on the parameter region in which there exists a strong separation of length and/or time scales. We found that the static one-dimensional autosolitons (stripes) break up into two-dimensional radially-symmetric autosolitons (spots).

For this coupled PDE system we construct a radially symmetric steady state solution and from a linearized stability analysis formulate criteria for which this base state can undergo either a Hopf bifurcation, a symmetry-breaking pitchfork (or Turing) bifurcation, or a.
