Travelling Wave Solutions and Conservation Laws of Fisher-Kolmogorov Equation
Lie symmetry group method is applied to study the Fisher-Kolmogorov equation. The symmetry group is given, and travelling wave solutions are obtained. Finally the conservation laws are determined.
متن کاملTravelling wave solutions of the generalized Benjamin-Bona-Mahony equation
A class of particular travelling wave solutions of the generalized Benjamin-BonaMahony equation are studied systematically using the factorization technique. Then, the general travelling wave solutions of Benjamin-Bona-Mahony equation, and of its modified version, are also recovered. Pacs:05.45.Yv, 52.35.Mw, 52.35.Sb, 02.30.Jr
متن کاملQualitative Properties and Existence of Solutions for a Generalized Fisher-like Equation
This paper is devoted to the study of an eigenvalue second order differential equation, supplied with homogenous Dirichlet conditions and set on the real line. In the linear case, the equation arises in the study of a reaction-diffusion system involved in disease propagation throughout a given population. Under some relations upon the real parameters and coefficients, we present some existence ...
متن کاملExact Travelling Wave Solutions for a Modified Zakharov–Kuznetsov Equation
The modied Zakharov–Kuznetsov (mZK) equation, ut + uux + uxxx + uxyy = 0, (1) represents an anisotropic two-dimensional generalization of the Korteweg–de Vries equation and can be derived in a magnetized plasma for small amplitude Alfvén waves at a critical angle to the undisturbed magnetic field, and has been studied by many authors because of its importance [1–5]. However, Eq. (1) possesses m...
متن کاملSome travelling wave solutions for a Generalized Benjamin-Bona-Mahony-Burgers equation by using MAXIMA program
In this paper we obtain symmetry reductions and exact solutions of a Generalized Benjamin-BonaMahony-Burgers equation using the potential symmetries method. We use the free software MAXIMA program symmgrp2009.max derived by W. Heremann to calculate the determining equations. Key–Words: Potential symmetries, Partial differential equation, Free software
