This article is devoted to deduce the expression and the main properties of the Green's function related to a general constant coefficients fractional difference equation coupled to Dirichlet conditions. In particular, it is proved that such function has constant sign on their set of definition and...

The system’s responses are obtained by solving the PDE, with Dirichlet boundary conditions, using a spectral numerical solver for each of the \(N = 100\) random forcing terms, sampled from a GP having a squared-exponential covariance kernel17. The learned Green’s function is displayed in ...
The differential equation alone is insufficient to determine Green's function uniquely, and it is necessary to apply additional conditions. These conditions are the radiation condition at infinity whenever the region extends to infinity and the boundary conditions. The chapter derives electromagnetic ...
This paper proposes a new Helmholtz decomposition based windowed Green function (HD-WGF) method for solving the time-harmonic elastic scattering problems on a half-space with Dirichlet boundary conditions in both 2D and 3D. The Helmholtz decomposition is applied to separate the pressure and shear wa...

Dirichlet problem in an arbitrary bounded domain where the boundary values are to be taken on in the generalized sense familiar from the work of Courant, Friedrichs, and others on the variational approach to elliptic differential equations.2 It is the first object of this note to outline the ...
In mathematical physics, Green’s function problems subjected to the boundary conditions and concentrated source satisfies∇2G(x,ξ)=δ(x-ξ),x∈Dwhere G(x, ξ) is the Green’s function and can be seen as the potential, ∇2 indicates the Laplacian operator. The boundary conditions of ...
