Abstract:This paper considers the class urn:x-wiley:dummy:media:mana201400056:mana201400056-math-0001 of all mappings of the form urn:x-wiley:dummy:media:mana201400056:mana201400056-math-0002 where h and g are analytic in the unit disk U, normalized by urn:x-wiley:dummy:media:mana201400056:mana201400056-math-0003, and such that urn:x-wiley:dummy:media:mana201400056:mana201400056-math-0004 is logharmonic with respect to an analytic self‐map a of U. A distortion estimate and the radius of starlikeness are obtained for this class. Additionally, a solution to the problem of minimizing the moments of order p over the class is found, as well as an estimate for arclength.
Keywords:Logharmonic mappings  rotationally starlike mappings  radius of starlikeness  distortion estimate  Primary: 30C35  30C45  Secondary: 35Q30
