A key model for predictive analysis, particularly in finance, is the Rössler system. This study
introduces an enhanced version of this model, incorporating minimum interest rates and …

The mathematical modeling of new emerging infectious diseases gaining high attention from
the researcher's around the world. We formulate a mathematical model with the statistical …

In this study, a novel method known as the Haar wavelet collocation method (HWCM) is
used to analyze the mathematical model of Chlamydia transmission in the United States. We …

Nowadays, the mathematical modeling of infectious diseases is a big trend worldwide. The
mathematical models help us to forecast future outbreaks of diseases in the presence of …

In this paper, our aim is to solve an optimal control problem by using an operator theoretic
approach in the sense of Caputo fractional derivative. We first reduce the fractional …

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 …

In this study, we developed a Caputo-Fractional Chlamydia pandemic model to describe the
disease's spread. We demonstrated the model's positivity and boundedness, ensuring …

Vaccination programs aimed at preventing the spread of the coronavirus appear to have a
significant global impact. In this research, we have investigated a mathematical model …

This paper investigates the fractional optimal control problem with a single delay in the state
by using the operator theoretic approach. In this approach, we first reduce the delay …

In enzyme kinetic chemical reaction, inhibitors are working as a regulators of the metabolism
of the systems and the biochemical activities as well. The main focus of this study is to …
