This paper deals with a new formulation of time fractional optimal control problems governed
by Caputo-Fabrizio (CF) fractional derivative. The optimality system for this problem is …

A human respiratory syncytial virus surveillance system was implemented in Florida in 1999,
to support clinical decision-making for prophylaxis of premature newborns. Recently, a local …

The optimal control strategy for time-varying epidemic models remains a wide open
research area. In this paper, the optimal vaccination strategy for a constrained time-varying …

The goal of this work is to study the optimal controls for the COVID-19 epidemic in Brazil. We
consider an age-structured SEIRQ model with quarantine compartment, where the controls …

We introduce a fractional order SIRS model with non-linear incidence rate. Existence of a
unique positive solution to the model is proved. Stability analysis of the disease free …

This paper uses transformed subsystem of ordinary differential equation seirs model, with
vital dynamics of birth and death rates, and temporary immunity (of infectious individuals or …

This paper deals with the study of a SEIRI epidemic model with relapse and general
incidence function. Using the next-generation matrix method, we have looked for the …

A state wide Human Respiratory Syncytial Virus (HRSV) surveillance system was
implemented in Florida in 1999 to support clinical decision-making for prophylaxis of …

We investigate the celebrated mathematical SICA model but using fractional differential
equations in order to better describe the dynamics of HIV-AIDS infection. The infection …

Optimal control problems reflecting the finding of effective quarantine strategies are
considered for two control SEIR~ type models describing the spread of the COVID-19 virus …
