2018
In this chapter we study the problem of existence and multiplicity of positive solutions for the nonlinear two-point boundary value ...

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.

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.

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.

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.

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.

Smoothing and Filling Holes with Dirichlet Boundary Conditions

2008
A commonly used method for the fitting of smooth functions to noisy data sets is the thin-plate spline method. Traditional thin-plate splines use radial basis functions and consequently requires the solution of a dense linear system of equations that grows with the number of data points.

A New Boundary Element Method for the Biharmonic Equation with Dirichlet Boundary Conditions

Advances in Computational Mathematics, 2003
The authors consider the biharmonic equation with Dirichlet boundary data on a bounded domain \(\Omega \) with Lipschitz boundary in \(\mathbb{R}^n\) (\(n=2\) or \(3\)). Using Almansi representation of \(w\) they transform the problem to the boundary integral equation \(L\Phi =F\) on \(\partial \Omega \). Then they prove that \(L:H^{-1}(\partial \Omega)

ζ-determinants of Laplacians with Neumann and Dirichlet boundary conditions

Journal of Physics A: Mathematical and General, 2005
In this paper, we derive a formula for the ratio of the \(\zeta\)-determinants of the Laplacian with Neumann and Dirichlet boundary conditions over a noncompact manifold with an infinite cylindrical end and a compact boundary in terms of the \(\zeta\)-determinant of the Dirichlet to Neumann map.
