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

Mathematical 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.

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

, 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 ...

Semigroups for Initial-Boundary Value Problems

, 2003
We review the theory of one-sided coupled operator matrices with a focus on evolution equations with inhomogeneous boundary conditions. (The original article had no abstract.)

Light-Front Quantisation as an Initial-Boundary Value Problem

, 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.

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

, 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 ...

Sources of quantum waves [PDF]

, 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

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

, 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.

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

Archive 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 ...

Mixed Initial-Boundary Value Problem for the Capillary Wave Equation

Advances in Mathematical Physics, 2016
We study the mixed initial-boundary value problem for the capillary wave equation: iut+u2u=∂x3/2u,  t>0,  x>0;  u(x,0)=u0(x),  x>0; u(0,t)+βux(0,t)=h(t),  t>0, where ∂x3/2u=(1/2π)∫0∞sign⁡x-y/x-yuyy(y) dy.
