Asymptotic stability of traveling wave solutions for nonlocal viscous conservation laws with explicit decay rates [PDF]

open access: yes, 2017
We consider scalar conservation laws with nonlocal diffusion of Riesz-Feller type such as the fractal Burgers equation. The existence of traveling wave solutions with monotone decreasing profile has been established recently (in special cases).

Traveling wave solution of the Hele-Shaw model of tumor growth with nutrient [PDF]

open access: yes, 2014
Several mathematical models of tumor growth are now commonly used to explain medical observations and predict cancer evolution based on images. These models incorporate mechanical laws for tissue compression combined with rules for nutrients availability

Utilizing the extended tanh-function technique to scrutinize fractional order nonlinear partial differential equations

open access: yesPartial Differential Equations in Applied Mathematics, 2023
In a range of nonlinear fields, for example molecular biology, physics in plasma, quantum mechanics, elastic media, nonlinear optics, the surface of water waves, and others, many complicated nonlinear behaviors can be pronounced using nonlinear ...

A Hamilton-Jacobi approach for front propagation in kinetic equations [PDF]

open access: yes, 2014
In this paper we use the theory of viscosity solutions for Hamilton-Jacobi equations to study propagation phenomena in kinetic equations. We perform the hydrodynamic limit of some kinetic models thanks to an adapted WKB ansatz.

Exact solutions for the ion sound Langmuir wave model by using two novel analytical methods

open access: yesResults in Physics, 2020
In the present paper, the system of equations for the ion sound and Langmuir waves (SEISLWs) is considered to obtain the new solitary wave solutions of the non-linear evolution equations. Here, we used the relatively two new analytical methods to achieve

(Non)linear instability of periodic traveling waves: Klein–Gordon and KdV type equations

open access: yesAdvances in Nonlinear Analysis, 2014
We prove the existence and nonlinear instability of periodic traveling wave solutions for the critical one-dimensional Klein–Gordon equation. We also establish a linear instability criterium for a KdV type system.

Traveling gravity water waves with critical layers [PDF]

open access: yes, 2016
We establish the existence of small-amplitude uni- and bimodal steady periodic gravity waves with an affine vorticity distribution, using a bifurcation argument that differs slightly from earlier theory.

Travelling waves in a nonlocal reaction-diffusion equation as a model for a population structured by a space variable and a phenotypical trait [PDF]

open access: yes, 2012
We consider a nonlocal reaction-diffusion equation as a model for a population structured by a space variable and a phenotypical trait. To sustain the possibility of invasion in the case where an underlying principal eigenvalue is negative, we ...

Generalized transition fronts for one-dimensional almost periodic Fisher-KPP equations [PDF]

open access: yes, 2016
This paper investigates the existence of generalized transition fronts for Fisher-KPP equations in one-dimensional, almost periodic media. Assuming that the linearized elliptic operator near the unstable steady state admits an almost periodic ...
