Metastable patterns for a reaction-diffusion model with mean curvature-type diffusion

نویسندگان

چکیده

Reaction-diffusion equations are widely used to describe a variety of phenomena such as pattern formation and front propagation in biological, chemical physical systems. In the one-dimensional model with balanced bistable reaction function, it is well-known that there persistence metastable patterns for an exponentially long time, i.e. time proportional $\exp(C/\e)$ where $C,\e$ strictly positive constants $\e^2$ diffusion coefficient. this paper, we extend results case when linear flux substituted by mean curvature operator both Euclidean Lorentz--Minkowski spaces. More precisely, models, prove existence states which maintain transition layer structure show speed layers small. Numerical simulations, confirm analytical results, also provided.

A Metastable Spike Solution for a Nonlocal Reaction-Diffusion Model

An asymptotic reduction of the Gierer Meinhardt activator-inhibitor system in the limit of large inhibitor diiusivity leads to a singularly perturbed non-local reaction diiusion equation for the activator concentration. In the limit of small activator diiusivity, a one-spike solution to this non-local model is constructed. The spectrum of the eigenvalue problem associated with the linearization...

Metastable Dynamics of Convection-diffusion-reaction Equations

Metastable dynamics, which qualitatively refers to physical processes that involve an extremely slow approach to their nal equilibrium states, is often associated with singularly perturbed convection-di usion-reaction equations. A problem exhibits metastable behavior when the approach to equilibrium occurs on a time-scale of order O(eC" ), where C > 0 and " is the singular perturbation paramete...

Convergence past Singularities to the Forced Mean Curvature Flow for a Modified Reaction-diffusion Approach

The approximation of forced mean curvature ow via a singularly perturbed double obstacle problem is studied. This approach diiers from the usual Allen-Cahn approximation because it is insensitive to the choice of the potential. We continue the investigation started in 6] by analyzing evolutions past singularities. We prove that the zero level sets of the solution to the double obstacle problem ...

An existence results on positive solutions for a reaction-diffusion model with logistics growth and indefinite weight

In this paper, using sub-supersolution argument, we prove an existence result on positive solution for an ecological model under certain conditions. It also describes the dynamics of the fish population with natural predation and constant yield harvesting. The assumptions are that the ecosystem is spatially homogeneous and the herbivore density is a constant which are valid assumptions for mana...

Patterns in reaction diffusion system

Reaction-Diffusion systems are important in the field of non-equilibrium phenomena with relevance to biological and synthetic pattern formation. While homogenous distribution of chemicals was always believed to be a stable state, the symmetry-breaking treatment by Turing on such systems in 1951 showed pattern formation could be more stable in certain cases. This paper reviews the treatment by T...
