An age-structured SVEAIR epidemiological model
Vasiliki Bitsouni, Nikolaos Gialelis, Vasilis Tsilidis
In this paper, we introduce and study an age-structured epidemiological compartment model and its respective problem, applied but not limited to the COVID-19 pandemic, in order to…
An inequality for completely monotone functions
Vasiliki Bitsouni, Nikolaos Gialelis, Dan-Stefan Marinescu
An inequality, which combines the concept of completely monotone functions with the theory of divided differences, is proposed. It is a straightforward generalization of a result,…
On the quasi-steady-state assumption in enzyme kinetics: rigorous analysis
Vasiliki Bitsouni, Nikolaos Gialelis, Ioannis G. Stratis
We study, from a purely quantitative point of view, the quasi-steady-state assumption for the fundamental mathematical model of the general enzymatic reaction: we re-establish, on…
A model for the outbreak of COVID-19: Vaccine effectiveness in a case study of Italy
Vasiliki Bitsouni, Nikolaos Gialelis, Ioannis G. Stratis
We present a compartmental mathematical model with demography for the spread of the COVID-19 disease, considering also asymptomatic infectious individuals. We compute the basic rep…
