Sufficient conditions for Janowski starlike functions [PDF]
Sufficient conditions for confluent (Kummer) hypergeometric function, generalized and normalized Bessel function of the first kind of complex order and integral operator to be subordinate to (1+Az)/(1+Bz) are obtained as applications.

Using a new linear extended multiplier q-Choi-Saigo-Srivastava operator we define a subclass subordination and the newly defined q-analogue of the Choi-Saigo-Srivastava operator to the class of analytic functions.

Radius of starlikeness through subordination
A normalized function f on the open unit disc is starlike (or convex) univalent if the associated function zf/(z)/f (z) (or 1+zf//(z)/f/(z)) is a function with positive real part.

Generalized q-Srivastava-Attiya operator on multivalent functions
In this article, we define a generalized q-integral operator on multivalent functions. It generalizes many known linear operators in Geometric Function Theory (GFT).

On the starlikeness of iterative integral operators [PDF]
The main object of the present paper is to investigate starlikeness of certain integral operators, which are defined here by means of iterative in the open disk $\mathbb{D}_R=\{z\in\mathbb{C}:|z|<R\}$ with $R\geq1$.

Certain sufficient conditions for starlikeness and convexity using a multiplier transformation
In the present paper, we study a differential subordination involving a multiplier transformation. Selecting different dominants to our main result, we obtain certain sufficient conditions for starlikeness and convexity of analytic functions.

In this paper we consider the linear operator L n : A → A, L nf (z) = (1 − λ) Dnf (z) + λInf (z) , where Dn is the S˘al˘agean differential operator and In is the S˘ala˘gean integral operator.

Letter to the Editor. Remarks on Some Inequalities for Polynomials [PDF]
MSC 2010: 30A10, 30C10, 30C80, 30D15, 41A17.In the present article, I point out serious errors in a paper published in Mathematica Balkanica three years ago. These errors seem to go unnoticed because some mathematicians are applying the results stated in

Inclusion and distortion properties for certain meromorphically multivalent functions
Two new subclasses Hp,k(λA;B) and Qp,k(λA;B) of meromorphically multivalent functions starlike with respect to k-symmetric points are introduced. Distortion bounds and inclusion relations for these subclasses are obtained.Mathematics Subject Classication
