Dirichlet and Neumann boundary conditions: What is in between?

Journal of Evolution Equations, 2003
Given an open set \(\Omega\) in \(\mathbb{R}^n\), an admissible measure on \(\partial \Omega\) is a Radon measure \(\mu\) on the Borel \(\sigma\)-field of some open subset \(\Gamma_{\mu}\) of \(\partial \Omega\) which does not charge sets of capacity zero.

Differaction for a neumann boundary condition

Communications in Partial Differential Equations, 1997
Let be a bounded open set in Rn and P be a constant coefficient operator of order 2 in Rn X Rt such that admits a strictly diffractive point. We calculate in this paper the principal symbol of the operatorK& transforming for a solution in the neighborhood of a strictly diffractive point We deduce from this calculation the principal symbol of the wave ...

Reproducing Kernel for Neumann Boundary Conditions

Punjab University Journal of Mathematics, 2022
We investigate a kernel space which is a particular class of Hilbert space. We discuss various properties of the reproducing kernel. In particular, our aim to construct kernel in reproducing space of the specific function space (Sobolev space) with the inner product and norm. Also, we derive the reproducing kernel for Neumann boundary conditions.

Estimates of Heat Kernels with Neumann Boundary Conditions

Potential Analysis, 2012
This paper is concerned with two-sided estimates for the heat kernels corresponding to general elliptic operators of the form \(Lu=\frac{1}{2}\nabla\cdot(A\nabla u)+b\cdot \nabla u-\nabla(\hat bu)+qu\) in a bounded domain \(D\subset \mathbb R^N\) subject to Robin boundary conditions: \(\frac{1}{2}\langle A\nabla u,n\rangle-\langle \hat b,n\rangle u=0\)

The stability of the Dirichlet and Neumann boundary conditions

Reports on Mathematical Physics, 1986
We investigate the stability of the Dirichlet and Neumann boundary conditions under the influence of an additive short range potential. We find that the Dirichlet boundary condition is stable while the Neumann boundary condition is not.

Neumann, Fourier and Mixed Boundary Conditions

2018
The GDM and its analysis are adapted here to cope with Neumann, Fourier and mixed boundary conditions. Properties of trace operators are detailed.

Interface evolution with Neumann boundary condition

Hokkaido University Preprint Series in Mathematics, 1992
Summary: We prove a comparison theorem for viscosity solutions of singular degenerate parabolic equations with Neumann boundary condition in a convex bounded domain. We also construct viscosity solutions for the Neumann problem in not necessarily convex domain. We apply our theorem to construct a global generalized evolution for interface equation with

Small sets for Neumann boundary conditions

Mathematische Nachrichten, 2008
AbstractFor an open set D ⊆ ℝn and a relatively closed subset E ⊆ D of Lebesgue measure zero, we investigate conditions for the property that Brownian motion with reflexion at the boundary on D and D \ E are the same. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
