In this paper, we apply optimal control theory to a novel coronavirus (COVID-19)
transmission model given by a system of non-linear ordinary differential equations. Optimal …

This study presents a new fuzzy fractional epidemiological model to investigate the Middle
East respiratory syndrome coronavirus on a complex heterogeneous network using fuzzy …

A new differentiation technique, fractional pseudospectral shifted Legendre differentiation
matrices (FSL D-matrices), was introduced. It depends on shifted Legendre polynomials …

We consider the fractional order epidemic model based on assumption that people will
recover after disease and may be infected again on a time interval of non fatal disease. Our …

Two schemes to find approximated solutions of optimal control problems of fractional order
(FOCPs) are investigated. Integration and differentiation matrices were used in these …

Studying the spread of epidemics and diseases is a worldwide problem especially during
the current time where the whole world is suffering from COVID‐19 pandemic. Antimicrobial …

In this paper, we provide a fractional-order delay differential model for coronavirus (CoV)
infection to give us best understand what causes the intensity of symptoms and illness of …

In this paper, we develop a fractional‐order differential model for the dynamics of immune
responses to SARS‐CoV‐2 viral load in one host. In the model, a fractional‐order derivative …

We present the existence of solutions for sequential Caputo–Hadamard fractional differential
equations (SC-HFDE) with fractional boundary conditions (FBCs). Known fixed-point …

In this paper, we present a new fractional epidemiological model on a heterogeneous
network to investigate Middle East respiratory syndrome (MERS-CoV), which is caused by a …
