In this article, we are studying a Covid-19 mathematical model in the fractal-fractional sense
of operators for the existence of solution, Hyers-Ulam (HU) stability and computational …

In this article, we consider a Covid-19 model for a population involving diabetics as a
subclass in the fractal–fractional (FF) sense of derivative. The study includes: existence …

The objective of this paper is to recommend an adjusted Susceptible-Exposed-Infectious-
Removed (SEIR) model that characterizes the temporal patterns of various individuals …

One of the global problems and a number of societal challenges in the areas of social life,
the economy, and international communications is COVID-19. In order to counteract the …

The transmission dynamics of COVID-19 is investigated through the prism of the Atangana-
Baleanu fractional model with acquired immunity. Harmonic incidence mean-type aims to …

Based on the data of COVID-19, this paper establishes the FCSEIR model for the spread
through data analysis and designs the related simulation software. Using the data from …

In a Banach space, we consider the nonlinear Langevin time-delay differential equations
with ψ-Caputo fractional derivatives. Using weighted norms involving Mittag-Leffler …

Fractional order control is one of the most important enablers of advanced closed loop
industrial automation systems. This paper presents a detailed bibliometric study of fractional …
