On certain analytic (Nevanlinna) functions.

Nevanlinna on Analytic Functions

On Sandwich theorems for certain classes of analytic functions

The purpose of this present paper is to derive some subordination and superordination results for certain analytic functions in the open unit disk. Relevant connections of the results, which are presented in the paper, with various known results are also considered.

On Certain Analytic Univalent Functions

We consider the class of analytic functions B(α) to investigate some properties for this class. The angular estimates of functions in the class B(α) are obtained. Finally, we derive some interesting conditions for the class of strongly starlike and strongly convex of order α in the open unit disk. 2000 Mathematics Subject Classification. Primary 30C45.

On Certain Classes of Multivalent Analytic Functions

In this paper we introduce the class B(p, n, μ, α) of analytic and p-valent functions to obtain some sufficient conditions and some angular properties for functions belonging to this class.

On the multivalency of certain analytic functions

We prove several relations of the type |arg{zf (z)/f (z)}| ≤ |arg{f (z)}| for functions satisfying some geometric conditions. 1 Introduction Let p be positive integer and let A(p) be the class of functions
