Analysis of Fuzzy-Fractional Fornberg–Whitham Models Using Extended He-Laplace Methodology

Journal of Mathematics
The Fornberg–Whitham equations (FWEs) are crucial models for capturing complicated wave dynamics, ranging from the ocean to plasma, and emphasizing the rich-interplay of nonlinearity and dispersion. These equations represent wave propagation in scenarios

Fuzzy fractional-order model of the novel coronavirus [PDF]

Advances in Difference Equations, 2020
AbstractIn this paper, a novel coronavirus infection system with a fuzzy fractional differential equation defined in Caputo’s sense is developed. By using the fuzzy Laplace method coupled with Adomian decomposition transform, numerical results are obtained for better understanding of the dynamical structures of the physical behavior of COVID-19.

Novel Evaluation of Fuzzy Fractional Biological Population Model

Journal of Function Spaces, 2022
This article discusses an iterative transformation method via fuzziness that mixtures the Laplace transform with the iterative iterative method. Using Caputo derivative operator, the proposed technique demonstrates the inherent reliability of fractional fuzzy biological population equations with initial fuzzy conditions.

A new fuzzy fractional order model of transmission of Covid-19 with quarantine class [PDF]

The European Physical Journal Plus, 2021
This paper is devoted to a study of the fuzzy fractional mathematical model reviewing the transmission dynamics of the infectious disease Covid-19. The proposed dynamical model consists of susceptible, exposed, symptomatic, asymptomatic, quarantine, hospitalized, and recovered compartments. In this study, we deal with the fuzzy fractional model defined

A Fuzzy Fractional Order Approach to SIDARTHE Epidemic Model for COVID‐19

Complexity, 2022
In this paper, a novel coronavirus SIDARTHE epidemic model system is constructed using a Caputo‐type fuzzy fractional differential equation. Applying Caputo derivatives to our model is motivated by the need to more thoroughly examine the dynamics of the model.

On a novel fuzzy fractional retarded delay epidemic model

AIMS Mathematics, 2022
<abstract><p>The traditional compartmental epidemic models such as SIR, SIRS, SEIR consider mortality rate as a parameter to evaluate the population changes in susceptible, infected, recovered, and exposed. We present a modern model where population changes in mortality are also considered as the parameter.
