tions and in Fourier analysis. Further examples will appear shortly. There are several ways to motivate the link between harmonic functions u(x,y), meaning solutions of the two-dimensional Laplace equation ∆u= ∂2u ∂x2 + ∂2u ∂y2 = 0, (2.3) and complex functions f(z). One natural starting point is the d’Alembert solution formula
