The aim of this work is to study the global existence in time of solutions for the tridiagonal system of reaction-diffusion by order mm. Our techniques of proof are based on compact semigroup methods and some L1{L}^{1}-estimates.

Spreading Speeds and Traveling Waves for Periodic Evolution Systems
2000 Math Subject Classification: 37C65, 37B55, 35K57, 35R10, 92D25The theory of spreading speeds and traveling waves for monotone autonomous semiflows is extended to periodic semiflows in the monostable case. Then these abstract results are applied to a

Analysis of iterative methods for solving a Ginzburg-Landau equation
. Very recently we have proposed to use a complex Ginzburg-Landau equation for high contrast inpainting, to restore higher dimensional (volumetric) data (which has applications in frame interpolation), improving sparsely sampled data and to fill in ...

Adaptive Computing by Memristor Circuits [PDF]
Neuromorphic circuits will be considered for energy efficient computing based on biological principles in future electronic systems. Thereby, memristors are assumed in neuron models and for synapses in several recent investigations in order to overcome ...

We propose a malaria model involving the sensitive and resistant strains, which is described by reaction-diffusion equations. The model reflects the scenario that the vector and host populations disperse with distinct diffusion rates, susceptible ...

Second-Order Phase Field Asymptotics For Unequal Conductivities
. We extend Karma and Rappel's improved asymptotic analysis of the phase field model to different diffusivities in solid and liquid. We consider both second-order "classical" asymptotics, in which the interface thickness is taken much ...

Sharp forced waves of degenerate diffusion equations in shifting environments
This article is concerned with the sharp forced waves for degenerate diffusion equations in a shifting environment. The degeneracy of diffusion usually causes the forced waves to become sharp.

This study deals with the global boundedness of a classical solution to a quasilinear two-species chemotaxis-competition model with nonlinear sensitivities in n≤3n\le 3. Due to the presence of nonlinear sensitivities, obtaining the necessary ‖w‖L∞\Vert w{

A Gradient Random Walk Method For Two-Dimensional Reaction-Diffusion Equations
. We present an extension to two space dimensions of the gradient random walk algorithm for reaction-diffusion equations. This family of algorithms is related closely to the random vortex method of computational fluid dynamics. Although the computational
