Abstract

The aim of the article is to study a sufficient condition for the classes SH k (m, b, λ1, λ2, δ, α) and CH k (m, b, λ1, λ2, δ, α) which are starlike and convex harmonic univalent functions with respect to k-symmetric, respectively. The necessary condition for f to be in the classes T SH k (m, b, λ1, λ2, δ, α) and T CH k (m, b, λ1, λ2, δ, α) will be studied. In addition, growth bounds for functions in T SH k (m, b, λ1, λ2, δ, α) will also be given.
