The Dirichlet Problem

 

Example 11.7. Find a function [Graphics:d2.txtgr1.gif] that is harmonic in
the upper half-plane Re z > 0, which takes on the boundary values:
[Graphics:d2.txtgr2.gif]

Solution:

[Graphics:d2.txtgr4.gif][Graphics:d2.txtgr3.gif]
[Graphics:d2.txtgr4.gif][Graphics:d2.txtgr5.gif]

A graph for the solution is:

 

A Dirichlet problem for the upper half plane.
