Old and new order of linear invariant family of harmonic mappings and the bound for Jacobian

Magdalena Sobczak-Kneć, Viktor V. Starkov, Jan Szynal

Abstract


The relation between the Jacobian and the orders of a linear invariant family of locally univalent harmonic mapping in the plane is studied. The new order (called the strong order) of a linear invariant family is defined and the relations between order and strong order are established.

Keywords


Planar harmonic mappings; order of a linear invariant family; Jacobian
