Mathematical Modelling of Plant-Pathogen-Herbivore Interaction Incorporating Allee Effect and Harvesting

Isaac K. Barasa, Samuel B. Apima & Amos O. Wanjara · Journal of Advances in Mathematics and Computer Science · 2022

Plant-pathogen-herbivore model describe interaction between plants, pathogens and herbivores. Plants are invaded by pathogens and herbivores while the herbivores are harvested by natural enemies such as predators and human. On the other hand, the abundance of food does not guaran...

Modification on Restrictive Taylor and Padé Approximations

M. S. Abdelwahed, Tamer M. Rageh, Aisha F. Fareed & Ahmed M. Youssef · Journal of Advances in Mathematics and Computer Science · 2022

We review Taylor approximation (TA), Padé approximation (PA), Restrictive Taylor approximation (RTA) and Restrictive Padé approximation (RPA). After comparing these four approximation methods with two other modified approximation methods: Modified Restrictive Taylor approximation...

The Modified Variational Iteration Method to Solve Linear Fractional Differential Equations

Nader M. Bassi & Anazeer Ismail · Journal of Advances in Mathematics and Computer Science · 2022

In this work we conceive a method of  how the Lagrange multiplier of modified Variational Iteration Method can be defined from Laplace transform, And we use this technique to solve both differential equations and FDEs with initial value conditions,  With Illustrative examples by ...

Numerical Solution of Landau-Lifshitz Equation in the Theory of Magnetic Elastic

Seyede Somaye Taghavi Takyar & Seyed Behnam Taghavi Takyar · Journal of Advances in Mathematics and Computer Science · 2022

In this paper we study Landau-Lifshitz equation which describe a nonlinear magnetic elastic in easy-axis ferromagnets. By means of numerical simulation a numerical solitonic solution to above mentioned equation with Standard Finite Difference (SFD) and NonStandard Finite Differen...

On Some Representations of the Euler-Mascheroni Constants

Gregory Abe-I-Kpeng, Mohammed Muniru Iddrisu & Kwara Nantomah · Journal of Advances in Mathematics and Computer Science · 2022

In this study, we derive a new representation for the Euler-Mascheroni constant and present various expressions for the classical Euler-Mascheroni constant related to the Riemann zeta function. Also, we proved that \(\gamma\)  is not algebraic if the Schanuel conjecture is true.

The Equitable Presentation for the Extended Quantum Algebra Uq(f(K, J))

Lixia Ye & Xuefeng Mei · Journal of Advances in Mathematics and Computer Science · 2022

Let Uq(f(K, J)) be an extended quantum enveloping algebra associated to sl2. In this paper, we display an equitable presentation for Uq(f(K, J)), in which all generators appear on a more equal footing. We also show that the equitable generators Y and Z are not invertible. Moreove...

Optimal Combinations of Control Strategies for Dynamics of Endemic Malaria Disease Transmission

Dereje Gutema Edossa, Alemu Geleta Wedajo & Purnachandra Rao Koya · Journal of Advances in Mathematics and Computer Science · 2022

In this study, a non-linear system of ordinary differential equation model that describe the dynamics of malaria disease transmission is derived and analyzed. Conditions are derived from the existence of disease-free and endemic equilibria. Basic reproduction number R0 of the mod...

Analytic Representation of Probability Density Function of Random Variable in Distributional Sense

Bedrije Bedjeti, Mejdin Saliji & Vesna Manova Eraković · Journal of Advances in Mathematics and Computer Science · 2022

In this paper, we have proved that the probability density function \(f(t)\) considered as a distribution has a Cauchy representation in \(O_\alpha^{\prime}\). The distribution space \(O_\alpha^{\prime}\) is intermediate space between \(E^{\prime}\) and \(D^{\prime}\).

Dynamics and Analysis of Chronic Brucellosis in Sheep

Paride O. Lolika & Mlyashimbi Helikumi · Journal of Advances in Mathematics and Computer Science · 2022

We proposed and studied a new fractional-order model for the transmission dynamics of brucellosis with a special focus on the sheep-to-sheep transmission. Two control strategies namely; culling and vaccination rate are incorporated in the model. We computed the basic reproduction...
