The parasitoid is a broad evolutionary association of hymenopteran insects which are well‐
known as biological control agents. Parasites are different from predators because parasites …

The present study is made to develop the fractional model of non-Newtonian Casson and
Williamson boundary layer flow in the fluid flow taking into account the heat flux and the slip …

The spectral collocation method based on the Vieta-Lucas polynomials is introduced here
for the flow of non-Newtonian Powell-Eyring fluid. The attentiveness is focused on some …

This article is devoted to deriving a new linearization formula of a class for Jacobi
polynomials that generalizes the third‐kind Chebyshev polynomials class. In fact, this new …

The main target of this work is presenting two efficient accurate algorithms for solving
numerically one of the most important models in physics and engineering mathematics …

This paper is devoted to proposing numerical algorithms based on the use of the tau and
collocation procedures, two widely used spectral approaches for the numerical treatment of …

A primary aim of this study is to examine and simulate a fractional Coronavirus disease
model by providing an efficient method for solving numerically this important model. In the …

Here, we provide a new method to solve the time-fractional diffusion equation (TFDE)
following the spectral tau approach. Our proposed numerical solution is expressed in terms …

Theoretical investigation of magnetohydrodynamics (MHD) Casson and Williamson fluid
flow and heat and mass transfer in laminar flow through a stretching sheet in the presence of …

In this research, we studied a mathematical model formulated with six fractional differential
equations to characterize a COVID-19 outbreak. For the past two years, the disease …
