Abstract
We study the subclass SHK (m,n,α,β) of SH(m,n,α,β) which is a new Salagean-type class with a differential operator defined by Salagean.One sufficient condition for functions in the subclass SHK (m,n,α,β) to be harmonic quasiconformal mappings and convex harmonic mappings is obtained.Meanwhile,the stability property and the δ-neighborhood of harmonic mappings for the subclass SHK (m,n,α,β) are considered.Our results improve and generalize the one made by B.Seker.关键词
