On harmonic functions by using ruscheweyh-type associated with differential operators

Abstract EN

By applying Ruscheweyh - type harmonic function on the class ASH(λ, α, k, γ), a new subclass ℋRq(m, α, k, γ) for harmonic univalent function in the unit disk D is introduced, Furthermore, some geometric properties are obtained such as distortion theorem, sufficient coefficient bounds, extreme points and convex combination conditions for aforementioned subclass.
