Successive Approximation for the Inhomogeneous Burgers Equation [PDF]

open access: yesJournal of Siberian Federal University. Mathematics & Physics, 2018
Summary: The inhomogeneous Burgers equation is a simple form of the Navier-Stokes equations. From the analytical point of view, the inhomogeneous form is poorly studied, the complete analytical solution depending closely on the form of the nonhomogeneous term.

Application of DRBEM for 2D sine-Gordon equation

open access: yesJournal of Taibah University for Science, 2021
This research paper introduces an application of dual reciprocity boundary element method (DRBEM) for the solution of sine-Gordon equation (SGE) in two-space dimension. Initially, the time derivatives are expanded using central difference schemes.

Euler–Darboux–Poisson Equation in Context of the Traveling Waves in a Strongly Inhomogeneous Media

open access: yesMathematics, 2023
The existence of traveling waves in an inhomogeneous medium is a vital problem, the solution of which can help in modeling the wave propagation over long distances. Such waves can be storm waves or tsunami waves in the seas and oceans.

Inflation driven by causal heat flux [PDF]

open access: yes, 1997
We find a simple inflationary solution in an inhomogeneous spacetime with heat flux. The heat flux obeys a causal transport equation, and counteracts the inflationary decrease of energy density.

Stokes-vector evolution in a weakly anisotropic inhomogeneous medium

open access: yes, 2007
Equation for evolution of the four-component Stokes vector in weakly anisotropic and smoothly inhomogeneous media is derived on the basis of quasi-isotropic approximation of the geometrical optics method, which provides consequent asymptotic solution of ...

A simple method considering the synergetic effect of space charge and inhomogeneous material conductivity for DC electric field computation

open access: yesHigh Voltage, 2022
The current continuity equation is usually applied to solve DC electric field distribution when there is inhomogeneous material conductivity due to temperature gradient or multi‐layer dielectrics.

On the Spinor Representation of Surfaces in Euclidean 3-Space

open access: yes, 1997
The aim of the present paper is to clarify the relationship between immersions of surfaces and solutions of the inhomogeneous Dirac equation. The main idea leading to the description of a surface M^2 by a spinor field is the observation that the ...
