چکیده

The emergence of the COVID-19 outbreak has caused a pandemic situation in over 210 countries. Controlling spread this disease proven difficult despite several resources employed. Millions hospitalizations and deaths have been observed, with thousands cases occurring daily many measures place. Due to complex nature COVID-19, we proposed system time-fractional equations better understand transmission disease. Non-locality model made fractional differential appropriate for modeling. Solving these types models is computationally demanding. Our generalized compartmental incorporates effective contact rate, transition quarantine disease-induced death natural recovery rate infected holistic study coronavirus A detailed analysis carried out, including existence uniqueness solutions, local global stability disease-free equilibrium (symmetry), sensitivity analysis. Furthermore, numerical solutions are obtained Adam–Bashforth–Moulton method developed fractional-order model. profile show that each incorporated parameters very important controlling COVID-19. Based on results different fractional-order, observe there seems be third or even fourth wave spike which currently

Time Series Modeling of Coronavirus (COVID-19) Spread in Iran

Various types of Coronaviruses are enveloped RNA viruses from the Corona-viridae family and part of the Coronavirinae subfamily. This family of viruses affects neurological, gastrointestinal, hepatic, and respiratory systems. Recently, a new memb-er of this family, named Covid-19, is moving around the world. The expansion of Covid-19 carries many risks, and its control requires strict planning ...

Modeling and analysis of the spread of the COVID-19 pandemic using the classical SIR model

In this paper modeling, analysis and prediction of novel epidemic of COVID-19 are concerned to identify effective spread parameters of it in Iran. For this purpose, the basic susceptible-infected-removed (SIR) model is used which has two parameters: the infection rate and remove rate. The occurrence of several maximum points in the Iranian data and the single peak of the SIR model makes it impo...

Existence and multiplicity of positive solutions for a coupled system of perturbed nonlinear fractional differential equations

In this paper, we consider a coupled system of nonlinear fractional differential equations (FDEs), such that both equations have a particular perturbed terms. Using emph{Leray-Schauder} fixed point theorem, we investigate the existence and multiplicity of positive solutions for this system.

Lie symmetry Analysis and Explicit Exact Dolutions of the Time Fractional Drinfeld-Sokolov-Wilson (DSW) System

In this study coupled system of nonlinear time fractional Drinfeld-Sokolov-Wilson equations, which describes the propagation of anomalous shallow water waves is investigated. The Lie symmetry analysis is performed on the model. Employing the suitable similarity transformations, the governing model is similarity reduced to a system of nonlinear ordinary differential equations with Erdelyi-Kober ...
