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 …

The entire world has been affected by the outbreak of COVID-19 since early 2020. Human
carriers are largely the spreaders of this new disease, and it spreads much faster compared …

To curtail and control the pandemic coronavirus (Covid-19) epidemic, there is an urgent
need to understand the transmissibility of the infection. Mathematical model is an important …

The present study is conducted to analyse the computational dynamical analysis of the
stochastic susceptible-infected-recovered pandemic model of the novel coronavirus. We …

In this paper a fractional optimal control problem was formulated for the outbreak of COVID-
19 using a mathematical model with fractional order derivative in the Caputo sense. The …

In the present study, a nonlinear delayed coronavirus pandemic model is investigated in the
human population. For study, we find the equilibria of susceptible-exposed-infected …

In this manuscript, the mathematical analysis of corona virus model with time delay effect is
studied. Mathematical modelling of infectious diseases has substantial role in the different …

Mathematical delay modelling has a significant role in the different disciplines such as
behavioural, social, physical, biological engineering, and bio-mathematical sciences. The …

Comorbidity is defined as the coexistence of two or more diseases in a person at the same
time. The mathematical analysis of the COVID-19 model with comorbidities presented …

As the corona virus (COVID-19) pandemic ravages socio-economic activities in addition to
devastating infectious and fatal consequences, optimal control strategy is an effective …
