ON A CRITERION FOR MULTIVALENT HARMONIC FUNCTIONS

Abstract

For normalized harmonic functions f z = h z + g z in the open unit disk, a criterion on the analytic part h z for f z to be p-valent and sense-preserving is discussed. Furthermore, several illustrative examples and images of f z satisfying the obtained condition are enumerated.
