Fractional Diffusion–Wave Equation with Application in Electrodynamics

open access: yesMathematics, 2020
We consider a diffusion–wave equation with fractional derivative with respect to the time variable, defined on infinite interval, and with the starting point at minus infinity.

Electrical analogous in viscoelasticity [PDF]

open access: yes, 2014
In this paper, electrical analogous models of fractional hereditary materials are introduced. Based on recent works by the authors, mechanical models of materials viscoelasticity behavior are firstly approached by using fractional mathematical ...

A discrete mechanical model of fractional hereditary materials [PDF]

open access: yes, 2013
Fractional hereditary materials are characterized for the presence, in the stress-strain relations, of fractional-order operators with order beta a[0,1]. In Di Paola and Zingales (J. Rheol.

Integrated Resolving Functions for Equations with Gerasimov–Caputo Derivatives

open access: yesSymmetry, 2023
The concept of a β-integrated resolving function for a linear equation with a Gerasimov–Caputo fractional derivative is introduced into consideration. A number of properties of such functions are proved, and conditions for the solvability of the Cauchy problem to linear homogeneous and inhomogeneous equations are found in the case of the existence of a

A Class of Quasilinear Equations with Distributed Gerasimov–Caputo Derivatives

open access: yesMathematics, 2023
Quasilinear equations in Banach spaces with distributed Gerasimov–Caputo fractional derivatives, which are defined by the Riemann–Stieltjes integrals, and with a linear closed operator A, are studied. The issues of unique solvability of the Cauchy problem to such equations are considered.

A Modified Fractional Derivative and its Application to Fractional Vibration Equation [PDF]

open access: yes, 2016
In this paper, a new modified definition of the fractional derivative is presented. The Laplace transform of the modified fractional derivative involves the initial values of the integer-order derivatives, but does not involve the initial values of the ...

Mathematical Models of Oscillators with Memory [PDF]

open access: yes, 2018
The chapter proposes a mathematical model for a wide class of hereditary oscillators, which is a Cauchy problem in the local formulation. As an initial model equation, an integrodifferential equation of Voltaire type was introduced, which was reduced by ...

An efficient method for the analytical study of linear and nonlinear time-fractional partial differential equations with variable coefficients [PDF]

open access: yes, 2023
The residual power series method is effective for obtaining approximate analytical solutions to fractional-order differential equations. This method, however, requires the derivative to compute the coefficients of terms in a series solution.
