Stieltjes-generated moment functionals and orthogonality: a transfer principle and an image theorem
Iván Area, Francisco J. Fernández, F. Adrián F. Tojo
We study the orthogonality induced by Stieltjes derivatives from the point of view of ordinary polynomial moment functionals. If \(g\) is a derivator and the Stieltjes monomials \(…
Exact discrete-adjoint optimization of trap timing and placement in a Stieltjes-time reaction-diffusion model: A Galicia case study
Francisco J. Fernández, Iván Area
Seasonal population models must combine diffusion, inactive periods and abrupt biological transfers while remaining differentiable with respect to localized interventions. We formu…
Fractional model of COVID-19 applied to Galicia, Spain and Portugal
Faical Ndairou, Ivan Area, Juan J. Nieto +2
A fractional compartmental mathematical model for the spread of the COVID-19 disease is proposed. Special focus has been done on the transmissibility of super-spreaders individuals…
Boundary value problem for the time-fractional telegraph equation with Caputo derivatives
M. O. Mamchuev
In this paper the Green formula for the operator of fractional differentiation in Caputo sense is proved. By using this formula the integral representation of all regular in a rect…
A note on the fractional logistic equation
I. Area, J. Losada, J. J. Nieto
In this short note, we show that the real function recently proposed by Bruce J. West [Exact solution to fractional logistic equation, Physica A 429 (2015) 103--108] is not an exac…
On fractional derivatives and primitives of periodic functions
I. Area, J. Losada, J. J. Nieto
In this paper we prove that the fractional derivative or the fractional primitive of a -periodic function cannot be a -periodic function, for any period ,…
