The Initial Boundary Value Problem for the Boltzmann Equation with Soft Potential [PDF]

open access: yesArchive for Rational Mechanics and Analysis, 2016
Boundary effects are central to the dynamics of the dilute particles governed by the Boltzmann equation. In this paper, we study both the diffuse reflection and the specular reflection boundary value problems for the Boltzmann equation with a soft ...

Stable radiation-controlling boundary conditions for the generalized harmonic Einstein equations [PDF]

open access: yes, 2006
This paper is concerned with the initial-boundary value problem for the Einstein equations in a first-order generalized harmonic formulation. We impose boundary conditions that preserve the constraints and control the incoming gravitational radiation by ...

Direct and inverse problems for thermal grooving by surface diffusion with time dependent Mullins coefficient

open access: yesMathematical Modelling and Analysis, 2021
We consider the Mullins’ equation of a single surface grooving when the surface diffusion is not considered as very slow. This problem can be formed by a surface grooving of profiles in a finite space region.

Sources of quantum waves [PDF]

open access: yes, 2000
Due to the space and time dependence of the wave function in the time dependent Schroedinger equation, different boundary conditions are possible. The equation is usually solved as an ``initial value problem'', by fixing the value of the wave function in

An Initial-Boundary Value Problem With New Technique of Piecewise Uniform Mesh [PDF]

open access: yesمجلة جامعة الانبار للعلوم الصرفة, 2023
The objective of my research is to establish facts and determine their significance. A new ε-convergent piecewise uniform mesh has been produced, by deriving a hybrid technique to find out the extent of subdomains (τ) of the singular boundary layers that

Asymptotics of solutions to the Navier-Stokes system in exterior domains [PDF]

open access: yes, 2013
We consider the incompressible Navier-Stokes equations with the Dirichlet boundary condition in an exterior domain of $\mathbb{R}^n$ with $n\geq2$. We compare the long-time behaviour of solutions to this initial-boundary value problem with the long-time ...

The initial boundary value problem for free-evolution formulations of general relativity [PDF]

open access: yes, 2016
We consider the initial boundary value problem for free-evolution formulations of general relativity coupled to a parametrized family of coordinate conditions that includes both the moving puncture and harmonic gauges.

Light-Front Quantisation as an Initial-Boundary Value Problem

open access: yes, 1993
In the light front quantisation scheme initial conditions are usually provided on a single lightlike hyperplane. This, however, is insufficient to yield a unique solution of the field equations.

Symmetry Analysis of Initial and Boundary Value Problems for Fractional Differential Equations in Caputo sense [PDF]

open access: yes, 2019
In this work we study Lie symmetry analysis of initial and boundary value problems for partial differential equations (PDE) with Caputo fractional derivative.
