A new collocation approach for a numerical treatment of multi order fractional differential equations

K. A. Bello*, A. Abdulkareem, O. T. Olotu, A. Abubakar, M. A. Adeyanju

This paper discusses the numerical solution of multi-order fractional differential equations by Exponentially fitted collocation method using two basis functions, namely, the Bernoulli polynomial and shifted Legendre polynomials. The fractional derivatives are expressed in the Caputo sense. The assumed solution is substituted into the problem considered an then manipulated. The resulting equation ...

Influence of Variable Viscosity and Slip Velocity on Unsteady Magnetohydrodynamic (Mhd) Flow of Blood Through a Stenosed Artery

A. Jimoh*

In this articles, influence of variable viscosity and slip velocity on unsteady MHD flow of blood through a stenosed artery are investigated, The blood viscosity is assumed to varying radially with hematocrit throughout the region of the artery. The analytical expressions for the flow characteristics are obtained using Galerkin’s and Fourth order Runge-Kutta methods. It was revealed from the resul...

Flux-Hardy Inequalities with Optimal Constants via Divergence and Rearrangements

M. A. Anise*, S. L. Soleye, K. Rauf

We develop sharp Hardy-type inequalities for boundary flux functionals generated by dilations of a fixed smooth set in R n. The method combines the divergence theorem with rearrangement bounds to reduce flux estimates to one-dimensional Hardy averages. Directional, divergence-form, and multi-flux inequalities are obtained in arbitrary dimension with the optimal constant p p−1 p , and sharpness is...

On the Existence of Fixed Points Satisfying Graphic Contraction Conditions on an Open Ball

K. F. Adedapo, K. Rauf, Ismail Musa*

This paper investigates the existence of fixed points in complete metric spaces through the application of Ciri´c-type fixed ´ point principles for (α, ψ)-contractive mappings. By formulating the problem within an open ball of a complete metric space, we establish sufficient conditions that guarantee the existence of fixed points under this generalized contractive framework. An illustrative exampl...
