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.

Inflow/outflow with Dirichlet boundary conditions for pressure in ISPH

Journal of Computational Physics, 2016
In the present work we propose a new algorithm for open boundary treatment in ISPH. In the literature a few models for open boundary conditions are available, but most of them are applied to weakly compressible SPH (WCSPH) only. In our method the inflow/outflow is driven by true Dirichlet boundary conditions of the projected pressure field.

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

A Linear Thermoelastic Plate Equation with Dirichlet Boundary Condition

Mathematical Methods in the Applied Sciences, 1997
Summary: We consider an initial-boundary value problem for a linear thermoelastic plate equation and we prove that the energy associated to the system decays exponentially to zero as time goes to infinity.

Use of Dirichlet boundary conditions for electron-atom scattering

Physical Review A, 1988
An R-matrix variational principle is presented in which the value of the function on the boundary surface is specified rather than its slope or logarithmic slope. Such a boundary condition appears to be convenient for treatment of the ionization process because, in principle, a boundary function can be built up by linear combination of inside solutions.
