WebJul 9, 2024 · Example 7.5.2 Find the Green’s function for the infinite plane. Solution From Figure 7.5.1 we have r − r′ = √(x − ξ)2 + (y − η)2. Therefore, the Green’s function from the last example gives G(x, y, ξ, η) = 1 4πln((ξ − x)2 + (η − y)2). Example 7.5.3 Find the Green’s function for the half plane, {(x, y) ∣ y > 0}, using the Method of Images.

Webfunctions times a kernel function we will call Green’s function, G. The ques-tion arises whether such a Green’s function and solution representation of a PDE in terms of an integral can be derived more directly. This question is motivated from ODE boundary value problems and associated Green’s func-tions. Web12.3 Expression of Field in Terms of Green’s Function Typically, one determines the eigenfunctions of a differential operator subject to homogeneous boundary conditions. That means that the Green’s functions obey the same conditions. See Sec. 11.8. But suppose we seek a solution of (L−λ)ψ= S (12.30) subject to inhomogeneous boundary ...
