WebI know that the existence of a solution to the above Dirichlet problem depends both on the regularity of ∂ U and on the choice of g. On the other side, Green's function is defined as G ( x, y) = Ψ ( x − y) − ϕ x ( y), x, y ∈ U and x ≠ y, where Ψ is the fundamental solution to Laplace's equation (and thus independent of g) and ϕ x satisfies Web§13.2 Green’s Functions for Dirichlet Boundary Value Problems Dirichlet problems for the two-dimensional Helmholtz equation take the form Lu = ∇2u+ k2u = F(x,y), (x,y)inA, … WebDec 26, 2014 · It is well known that for Dirichlet problem for Laplace equation on balls or half-space, we could use the green function to construct a solution based on the boundary data.
