On a Class of Univalent Functions
We consider the class of univalent functions f(z)= z+a3z3+a4z4+··· analytic in the unit disc and satisfying |(z2f ′(z)/f 2(z))−1|< 1, and show that such functions are starlike if they satisfy |(z2f ′(z)/f 2(z))−1|< (1/√2).
متن کاملOn certain subclasses of univalent $p$-harmonic mappings
Inthis paper, the main aim is to introduce the class $mathcal{U}_p(lambda,alpha,beta,k_0)$ of $p$-harmonic mappings togetherwith its subclasses $mathcal{U}_p(lambda,alpha,beta,k_0)capmathcal {T}_p$ and $mathcal{U}_p(lambda,alpha,beta,k_0)capmathcal {T}_p^0$, andinvestigate the properties of the mappings in these classes. First,we give a sufficient condition for mappings to be in $mathcal{U}_p(l...
متن کاملOn a class of univalent functions
We consider the class of univalent functions defined by the conditions f(z)/z ≠ 0 and |(z/f(z))′′| ≤α,|z|< 1, where f(z)= z+··· is analytic in |z|< 1 and 0<α≤ 2.
متن کاملOn Certain Class of Harmonic Univalent Functions
Abstract -A complex-valued functions that are univalent and sense preserving in the unit disk U can be written in the form ( ) ( ) ( ) f z h z g z , where U(z) and g(z) are analytic in. We will introduced the operator D which defined by convolution involving the polylogarithms functions. Using this operator, we introduce the class HP(,, n) by generalized derivative operator of harmonic un...
متن کاملPlanar Harmonic Univalent and Related Mappings
The theory of harmonic univalent mappings has become a very popular research topic in recent years. The aim of this expository article is to present a guided tour of the planar harmonic univalent and related mappings with emphasis on recent results and open problems and, in particular, to look at the harmonic analogues of the theory of analytic univalent functions in the unit disc.
