چکیده

The existence, uniqueness, and global exponential stability of traveling wave solutions of a class of nonlinear and nonlocal evolution equations are established. It is assumed that there are two stable equilibria so that a tr aveling wave is a solution that connects them. A basic assumption is the comparison principle: a smaller initial value produces a smaller solution. When applied to di erential equations or integro-di erential equations, the result recovers and/or complements a number of existing ones.

Traveling Waves of Some Symmetric Planar Flows of Non-Newtonian Fluids

We present some variants of Burgers-type equations for incompressible and isothermal planar flow of viscous non-Newtonian fluids based on the Cross, the Carreau and the power-law rheology models, and on a symmetry assumption on the flow. We numerically solve the associated traveling wave equations by using industrial data and in order to validate the models we prove existence and uniqueness of ...

Existence, Asymptotics and Uniqueness of Traveling Waves for Nonlocal Diffusion Systems with Delayed Nonlocal Response

Abstract. In this paper, we deal with the existence, asymptotic behavior and uniqueness of travelingwaves for nonlocal diffusion systems with delay and global response. We first obtain the existence of traveling wave front by using upperlower solutions method and Schauder’s fixed point theorem for c > c∗ and using a limiting argument for c = c∗. Secondly, we find a priori asymptotic behavior of...

Global Asymptotic Stability of Traveling Waves in Delayed Reaction-Diffusion Equations

The existence and comparison theorem of solutions is first established for the quasimonotone delayed reaction-diffusion equations on R by appealing to the theory of abstract functional differential equations. The global asymptotic stability, Liapunov stability and uniqueness of traveling wave solutions are then proved by the elementary superand sub-solution comparison and squeezing methods. Sup...

Existence, Uniqueness and Stability of Traveling Wavefronts for Nonlocal Dispersal Equations with Convolution Type Bistable Nonlinearity

This article concerns the bistable traveling wavefronts of a nonlocal dispersal equation with convolution type bistable nonlinearity. Applying a homotopy method, we establish the existence of traveling wavefronts. If the wave speed does not vanish, i.e. c 6= 0, then the uniqueness (up to translation) and the globally asymptotical stability of traveling wavefronts are proved by the comparison pr...

Existence and Stability of Traveling Waves for a Class of Nonlocal Nonlinear Equations

In this article we are concerned with the existence and orbital stability of traveling wave solutions of a general class of nonlocal wave equations: utt − Luxx = B(±|u|u)xx, p > 1. The main characteristic of this class of equations is the existence of two sources of dispersion, characterized by two coercive pseudo-differential operatorsL and B. Members of the class arise as mathematical models ...
