- 2. In this problem we prove that if Au(x, y) = 0 for all points in the x, y plane and u is a bounded function then u must be a constant. Hence if u is harmonic on the whole plane and non-constant then u must approach oo or -o along some direction. (1) Suppose u is bounded in the sense that Ju(x, y)| < M for all (x, y).
