Class Objectives
/Class Outline |
To acquire basic knowledge of harmonic function theory in a plane, we begin with expositions of some properties and behavior of harmonic functions, and then investigate some basic properties of sub/super harmonic functions and explain the Perron method concerning the Dirichlet problem in a general domain. If time permits, the proof of the Riemann mapping theorem is given. |
