Analytical Approach to Space- and *** Burgers Equations

引用

Chinese Physics Letters 2010年第9期27卷 38-41页

作者： Ahmet Yildirim syed tauseef mohyud-din Department of Mathematics Ege University 35100 Bornova-Izmir Turkey HITEC University Taxila Cantt Pakistan

A scheme is developed to study numerical solution of the space- and time-fractional Burgers equations under initial conditions by the homotopy analysis method. The fractional derivatives are considered in the Caputo sense. The solutions are given in the form of series with easily computable terms. Numerical solutions are calculated for the fractional Burgers equation to show the nature of solution as the fractional derivative parameter is changed.

Numerical Solution of the Three-Dimensional Helmholtz Equation

Chinese Physics Letters 2010年第6期27卷 1-4页

作者： syed tauseef mohyud-din Ahmet Ylldlrim Department of Basic Sciences HITEC University Taxila Cantt Pakistan Department of Mathematics Ege University 35100 Bornova-izmir Turkey

We apply the homotopy analysis method to solve the nonhomogeneous multidimensional partial differential equation model problem. The analytic solutions are calculated in terms of convergent series with easily computable components. The nonhomogeneous problem is quickly solved by observing the self-canceling ＂noise＂ terms whose sum vanishes in the limit. Numerical results clearly reveal the complete reliability and efficiency of the proposed algorithm.

作者： Md.Nur Alam Md.Ali Akbar syed tauseef mohyud-din Department of Mathematics Pabna University of Science and Technology Department of Applied Mathematics University of Rajshahi Department of Mathematics HITEC UniversityTaxila Cantt

In this article, a novel （G＇/G）-expansion method is proposed to search for the traveling wave solutions of nonlinear evolution equations. We construct abundant traveling wave solutions involving parameters to the Boussinesq equation by means of the suggested method. The performance of the method is reliable and useful, and gives more general exact solutions than the existing methods. The new （G＇/G）-expansion method provides not only more general forms of solutions but also cuspon, peakon, soliton, and periodic waves.

On biological population model of fractional order

引用

International Journal of Biomathematics 2016年第5期9卷 107-119页

作者： syed tauseef mohyud-din Ayyaz Ali Bandar Bin-Mohsin Department of Mathematics HITEC University Taxila Pakistan Department of Mathematics College of Sciences King Saud University Riyadh Saudi Arabia

In this paper, we extensively studied a mathematical model of biology. It helps us to understand the dynamical procedure of population changes in biological population model and provides valuable predictions. In this model, we establish a variety of exact solutions. To study the exact solutions, we used a fractional complex transform to convert the particular partial differential equation of fractional order into corresponding partial differential equation and modified exp-function method is implemented to investigate the nonlinear equation. Graphical demonstrations along with the numerical data reinforce the efficacy of the used procedure. The specified idea is very effective, unfailing, well-organized and pragmatic for fractional PDEs and could be protracted to further physical happenings.
