Enforce the Dirichlet boundary condition by volume constraint in Point Integral method [PDF]

, 2015
Recently, Shi and Sun proposed Point Integral method (PIM) to discretize Laplace-Beltrami operator on point cloud. In PIM, Neumann boundary is nature, but Dirichlet boundary needs some special treatment.

The Meyers Estimates for Domains Perforated along the Boundary

Mathematics, 2021
In this paper, we consider an elliptic problem in a domain perforated along the boundary. By setting a homogeneous Dirichlet condition on the boundary of the cavities and a homogeneous Neumann condition on the outer boundary of the domain, we prove ...

Effect of boundary conditions on the dynamics of a pulsesolution for reaction-diffusion systems

Networks and Heterogeneous Media, 2013
We consider pulse-like localized solutions for reaction-diffusion systems ona half line and impose various boundary conditions at one end of it.It is shown that the movement of a pulse solutionwith the homogeneous Neumann boundary condition is completely

Solution to the Dirichlet Problem of the Wave Equation on a Star Graph

Mathematics, 2023
In this paper, the solution to the Dirichlet problem for the wave equation on the star graph is constructed. To begin, we solve the boundary value problem on the interval (on one edge of the graph).

Schroedinger functional formalism with domain-wall fermion [PDF]

, 2006
Finite volume renormalization scheme is one of the most fascinating scheme for non-perturbative renormalization on lattice. By using the step scaling function one can follow running of renormalized quantities with reasonable cost.

On the dynamics in the AdS/BCFT correspondence

Journal of High Energy Physics, 2022
We consider a perturbation of the Einstein gravity with the Neumann boundary condition, which is regarded as an end of the world brane (ETW brane) of the AdS/BCFT correspondence, in the AdS d+1 spacetime with d ≥ 3.

An infection age-space-structured SIR epidemic model with Dirichlet boundary condition

Mathematical Modelling of Natural Phenomena, 2019
In this paper, we are concerned with the global asymptotic behavior of an SIR epidemic model with infection age-space structure. Under the homogeneous Dirichlet boundary condition, we first reformulate the model into the coupled reaction-diffusion and ...

Absorption semigroups and dirichlet boundary conditions

Mathematische Annalen, 1993
Given a positive \(C_ 0\)-semigroup \(T\) on \(L^ p(X)\) and an arbitrary non-negative potential \(V\), an absorption semigroup \(T_ V\) is constructed as a \(C_ 0\)-semigroup on \(L^ p(X_ V)\) for a certain subset \(X_ V\) of \(X\). Information is obtained about \(X_ V\).

The effect of a new two-point nonlocal condition on the eigenvalue problem of the difference scheme for an elliptic partial differential equation

Alexandria Engineering Journal, 2022
In this paper, a new form of two-point nonlocal boundary conditions is presented. This condition generalizes a Dirichlet condition at one boundary and a mixed condition at the other one.
