420 Chapter 7 Conformal Mappings ∇ φ = 0 2 φ = k0 θ = π x 1 θ y z φ = k1 θ = 0 Figure 7.35 Dirichlet problem (1) 7.4 Poisson Integral Formulas The success of7.4 using a conformal mapping to solve a boundary-value problem associated with Laplace’s equation often depends on the abilityto solve a related boundary-value problem in a simple domain such as the upper half-plane y > 0 or the open unit disk |z| < 1. In this section we present two important integral formulas for solving a Dirichlet problem in these domains. x Formula for the Upper Half-Plane We begin byinvestigating the following Dirichlet problem: Solve: ∂2φ ∂x2 + ∂2φ =0, −∞
y ∇ φ = 0 2 x 1 x 2 x n φ = k0 φ = k1 φ = k2 φ = kn Figure 7.36 Dirichlet problem (6) x 7.4 Poisson Integral Formulas 421 We next verifythat the boundaryconditions of (1) are satisfied byφ(x, y). Assume that z is in the interval (x1, ∞) in the real axis. That is, z = x +0i with x1
