Convolution of two Harmonic Mappings in the Right-half Plane

Abstract

This paper is to give a univalent criterion and a geometric
property of the convolution of two right half-plane harmonic mappings
f0(z) and f(z), here f0(z) is canonical and the second complex dilatation w(z) of f(z) is of the form w(z) = - 1z--az a 1z--bz b .
