This study presents the problem of spreading a disease that is not fatal in a population by
using the Morgan-voyce collocation method. The main aim of this paper is to find the exact …

In this paper, we deal with singularly perturbed Fredholm integro differential equation
(SPFIDE) with mixed boundary conditions. By using interpolating quadrature rules and …

In this article, we present a study about the evolution of the COVID-19 pandemic in Turkey.
The modelling of a new virus named SARS-CoV-2 is considered by an SIR model consisting …

The aim of this study is to present the evolution of COVID‐19 pandemic in Turkey. For this,
the SIR (Susceptible, Infected, Removed) model with the fractional order derivative is …

In this study, the approximate solution of the nonlinear differential equation with variable
delays is investigated by means of a collocation method based on the truncated Pell-Lucas …

This paper introduces a Pell-Lucas collocation method for solving Volterra integral
equations of the second kind. The proposed method employs collocation points and …

Purpose This study aims to treat a novel system of Volterra integro-differential equations with
multiple delays and variable bounds, constituting a generic numerical method based on the …
