A fractional model of cancer-immune system with Caputo and Caputo–Fabrizio derivatives [PDF]

open access: yesThe European Physical Journal Plus, 2021
Recently, it is important to try to understand diseases with large mortality rates worldwide, such as infectious disease and cancer. For this reason, mathematical modeling can be used to comment on diseases that adversely affect all people. So, this paper discuss mathematical model presented for the first time that examines the interaction between ...

On Riemann‐Liouville and Caputo Derivatives [PDF]

open access: yesDiscrete Dynamics in Nature and Society, 2011
Recently, many models are formulated in terms of fractional derivatives, such as in control processing, viscoelasticity, signal processing, and anomalous diffusion. In the present paper, we further study the important properties of the Riemann‐Liouville (RL) derivative, one of mostly used fractional derivatives.

Fractional Telegraph Equation with the Caputo Derivative

open access: yesFractal and Fractional, 2023
The Cauchy problem for the telegraph equation (Dtρ)2u(t)+2αDtρu(t)+Au(t)=f(t) (0<t≤T,0<ρ<1, α>0), with the Caputo derivative is considered. Here, A is a selfadjoint positive operator, acting in a Hilbert space, H; Dt is the Caputo fractional derivative.

A Note on Caputo’s Derivative Operator Interpretation in Economy [PDF]

open access: yesJournal of Applied Mathematics, 2018
We propound the economic idea in terms of fractional derivatives, which involves the modified Caputo’s fractional derivative operator. The suggested economic interpretation is based on a generalization of average count and marginal value of economic indicators.

Fractional hamilton formalism within caputo’s derivative [PDF]

open access: yesCzechoslovak Journal of Physics, 2006
In this paper we develop a fractional Hamiltonian formulation for dynamic systems defined in terms of fractional Caputo derivatives. Expressions for fractional canonical momenta and fractional canonical Hamiltonian are given, and a set of fractional Hamiltonian equations are obtained.
