Computable solution of fractional kinetic equations using Mathieu-type series

open access: yesAdvances in Difference Equations, 2019
The Mathieu series appeared in the study of elasticity of solid bodies in the work of Émile Leonard Mathieu. Since then numerous authors have studied various problems arising from the Mathieu series in several diverse ways.

Influence of Material Defects on the Dynamic Stability of the Bernoulli-Euler Beam [PDF]

open access: yesArchives of Metallurgy and Materials, 2021
The paper presents the results of tests on dynamic stability of Bernoulli-Euler beam with damages. Damages (cracks) were modeled using three rotational springs.

Evolution of Cosmological Perturbation in Reheating Phase of the Universe [PDF]

open access: yes, 1996
The evolution of the cosmological perturbation during the oscillatory stage of the scalar field is investigated. For the power law potential of the inflaton field, the evolution equation of the Mukhanov's gauge invariant variable is reduced to the ...

Dynamical diffraction in sinusoidal potentials: uniform approximations for Mathieu functions [PDF]

open access: yes, 2000
Eigenvalues and eigenfunctions of Mathieu's equation are found in the short wavelength limit using a uniform approximation (method of comparison with a `known' equation having the same classical turning point structure) applied in Fourier space.

On the singular spectrum of the Almost Mathieu operator. Arithmetics and Cantor spectra of integrable models [PDF]

open access: yes, 1999
I review a recent progress towards solution of the Almost Mathieu equation (A.G. Abanov, J.C. Talstra, P.B. Wiegmann, Nucl. Phys. B 525, 571, 1998), known also as Harper's equation or Azbel-Hofstadter problem. The spectrum of this equation is known to be

Numerical solution of fractional Mathieu equations by using block-pulse wavelets

open access: yesJournal of Ocean Engineering and Science, 2019
In this paper, we introduce a method based on operational matrix of fractional order integration for the numerical solution of fractional Mathieu equation and then apply it in a number of cases.
