in this article, we apply the multiquadric radial basis function (rbf) interpo-lation method for nding the numerical approximation of traveling wave solu-tions of the kawahara equation. the scheme is based on the crank-nicolsonformulation for space derivative. the performance of the method is shown innumerical examples.

Recent biological research has sought to understand how biochemical signaling pathways, such as the mitogen-activated protein kinase (MAPK) family, influence the migration of a population of cells during wound healing. Fisher’s Equation has been used extensively to model experimental wound healing assays due to its simple nature and known traveling wave solutions. This partial differential equa...

Abstract In this work, we investigate for finding exact solitary wave solutions of the (2 + 1)-dimensional Zoomeron equation and the Tzitzeica–Dodd–Bullough (TDB) equation by using the direct algebraic method. The direct algebraic method is promising for finding exact traveling wave solutions of nonlinear evolution equations in mathematical physics. The competence of the methods for constructin...

This paper focuses on regular traveling waves, or waves that propagate smoothly, in a one-dimensional network of theta neurons. We show that when coupling strength is sufficiently large, there exist two traveling wave solutions for this network. Moreover, the cells in the network spike more than one time after joining the wave; that is, some form of synaptic depression or other adaptive mechani...

We examine the existence of traveling wave solutions for a continuum neuronal network modeled by integro-differential equations. First, we consider a scalar field model with a general smooth firing rate function and a spatiotemporally varying stimulus. We prove that a traveling front solution that is locked to the stimulus exists for a certain interval of stimulus speeds. Next, we include a slo...

This paper deals with entire solutions of a bistable reaction-diffusion equation for which the speed of the traveling wave connecting two constant stable equilibria is zero. Entire solutions which behave as two traveling fronts approaching, with super-slow speeds, from opposite directions and annihilating in a finite time are constructed by using a quasiinvariant manifold approach. Such solutio...

From a Vlasov-type kinetic equation with nonlocal braking and acceleration forces, taken as a traffic model for higher densities, we derive macroscopic equations generalizing the second order model of conservation laws suggested by Aw and Rascle [1] and Zhang [2]. The nonlocality remains present in these equations, but more conventional, local equations are derived by using suitable Taylor expa...
