In this paper, a fractional order nonlinear model for Omicron, known as B. 1.1. 529 SARS-
Cov-2 variant, is proposed. The COVID-19 vaccine and quarantine are inserted to ensure …

The time delay between the conversion of susceptible individuals into infected individuals is
considered for the purpose of assessing the stability of the fractional order delay …

In order to examine the dynamics of the Omicron variant, this paper uses mathematical
modelling and analysis of a SQIRV model, taking into account the delay in the conversion of …

This research examines the transmission dynamics of the Omicron variant of COVID-19
using SEIQIcRVW and SQIRV models, considering the delay in converting susceptible …

In this study, an epidemic mathematical model for Omicron, denoted as B. 1.1. 529 SARS-
Cov-2 Variant, is constructed. Covid-19 vaccines are considered here to ensure the host …

In this study, we propose a fractional-order epidemic model of the Omicron variant. We
provide analyses of the solutionʼs positivity, boundedness, existence, and uniqueness. The …

This paper presents the construction of a dynamic nonlinear SSASPAIR mathematical model
for cancer, which is caused by smoking and drug addiction. The fundamentals of positivity …
