Abstract
A 2p times continuously differentiable complex-valued mapping F = u + i v in a domain D subset of C is polyharmonic if F satisfies the polyharmonic equation Delta ... Delta (sic)F p = 0 p is an element of N+ represents the complex Laplacian operator. The main aim of this paper is to introduce a subclasses of polyharmonic mappings. Coefficient conditions, distortion bounds, extreme points, of the subclasses are obtained. (C) 2017 All rights reserved.
