Description
Summary:Honoring Peter Duren’s work on harmonic functions, the cover of this volume visualizes a complex harmonic polynomial which has the maximum number of zeros among all such polynomials of degree 5. In this note we explain how properties of this function are encoded in its image and sketch some background.
