Linear Parabolic Problems in Random Moving Domains

open access: yes, 2018
We consider linear parabolic equations on a random non-cylindrical domain. Utilizing the domain mapping method, we write the problem as a partial differential equation with random coefficients on a cylindrical deterministic domain.

Relativistic Compact Objects in Isotropic Coordinates

open access: yes, 2005
We present a matrix method for obtaining new classes of exact solutions for Einstein's equations representing static perfect fluid spheres. By means of a matrix transformation, we reduce Einstein's equations to two independent Riccati type differential ...

Flow Equations for Electron-Phonon Interactions

open access: yes, 1996
A recently proposed method of continuous unitary transformations is used to eliminate the interaction between electrons and phonons. The differential equations for the couplings represent an infinitesimal formulation of a sequence of Fr\"ohlich ...

Solution of conformable fractional ordinary differential equations via differential transform method [PDF]

open access: yesOptik, 2017
Recently, a new fractional derivative called the conformable fractional derivative is given which is based on the basic limit definition of the derivative in [1]. Then, the fractional versions of chain rules, exponential functions, Gronwall's inequality, integration by parts, Taylor power series expansions is developed in [2].

Numerical implementation of differential transformations method for integro-differential equations

open access: yesInternational Journal of Computer Mathematics, 2010
Differential transformation (DT) is one of the numeric methods for solving differential equations. The advantage of this method is to transform the differential equation into algebraic ones. The aim of this article is to present a comparative study of the DT for solving of linear or nonlinear integro-differential equations.

Solving Coupled Fractional Differential Equations Using Differential Transform Method.

open access: yesTurkish Journal of Computer and Mathematics Education (TURCOMAT), 2021
This paper presents the solution of coupled equations which are of fractional order using differential transform method. In this paper we extend the scope of differential transform method to system of fractional differential equations so that we get the analytical solutions.
