Coefficient Problem for Certain Subclass of Analytic functions using Quasi-Subordination
An analytic function is quasi-subordinate to an analytic function , in the open unit disk if there exist analytic function and , with (0) = 0 and 1 such that Certain subclasses of analytic univalent functions associated with quasi-subordination are defined and the bounds for the Fekete-Szego coefficient functional for functions belonging to these subclasses are derived.
On Coefficient Estimates and Neighbourhood Problem for Generalized Sakaguchi Type Functions
In the present investigation, we introduce a new class of analytic functions with negative coefficients. The various results obtained here for this function include coefficient estimate and inclusion relationships involving the neighbourhoods of the analytic function.
Certain New Subclasses of Analytic Univalent Functions in the Unit Disk
Introduction of new subclasses and of analytic functions with negative co-efficents defined in the unit disk. We estimate some properties of functions in these classes and obtain Co-efficient bounds, Neighbourhood and Integral means inequality for the function f(z) under these classes.
