Variational Formulation of the Dirichlet Boundary Condition

IEEE Transactions on Microwave Theory and Techniques, 1972
The functional whose stationary point is furnished by the solution of Poisson's equation under mixed, Neumann, and Dirichlet boundary conditions within a homogeneous region is presented. The Dirichlet condition is formulated as a natural one, thus removing a considerable restriction on acceptable trial functions.

Hybrid fractional diffusion problem with Dirichlet boundary conditions

2021
Summary: In this research, we discuss the construction of the analytic solution of homogeneous initial boundary value problem including partial differential equations of fractional order. Since homogeneous initial boundary value problem involves Hybrid fractional order derivative, it has classical initial and boundary conditions. By means of separation

Competition systems with Dirichlet boundary conditions

Journal of Mathematical Biology, 1982
A class of semilinear parabolic systems describing competing species is investigated with homogeneous Dirichlet or boundary conditions of the third kind; existence and attractivity properties of equilibrium solutions are proved by monotonicity methods.

From Neuman to Dirichlet boundary conditions

AIP Conference Proceedings, 2007
The Dirichlet boundary conditions for the end‐point of the open string define Dp‐brane. It is parameterized by the rest of coordinates, with Neuman boundary conditions. The relations between background fields can produce the local gauge symmetries of the world‐sheet action.

Classical Solutions for SPDEs with Dirichlet Boundary Conditions

2002
The aim of the paper is to prove some significative results for a given class of stochastic evolution equations by means of a suitable adaptation of techniques (the stochastic characteristics method and a Ito-type formula for backward diffusions) which are already known in the literature, but not so widely used.

Dirichlet-to-Neumann boundary conditions for multiple scattering problems

Journal of Computational Physics, 2003
This paper deals with a Dirichlet-to-Neumann condition which is derived for the numerical solution of time-harmonic multiple scattering problems, where the scatterer consists of several disjoints components.

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.

The Dirichlet Problem With Denjoy-Perron Integrable Boundary Condition

Canadian Mathematical Bulletin, 1985
AbstractThe Poisson integral of a Denjoy-Perron integrable function defined on the boundary of an open disc is harmonic in this disc. Moreover, almost everywhere on the boundary, the nontangential limits of the integral coincide with the boundary condition. This extends the classical result for Lebesgue integrable boundary conditions.
