On the upper bounds of Hankel determinants for some subclasses of univalent functions associated with sine functions

Muhammet KAMALİ | Alina RISKULOVA

Let a normalized analytic function be given on the open unit disk. In this paper, we define and consider some familiar subsets of analytic functions associated with sine functions in the region of unit disk on the complex plane. For these classes, we aim to find the upper bounds of the modules of the Hankel determinants obtained from the coefficients of the functions belonging to some classes defined by subordination.

ON BOUNDS OF TOEPLITZ DETERMINANTS FOR A SUBCLASS OF ANALYTIC FUNCTIONS

Muhammet KAMALİ | Alina RISKULOVA

In the present article, our aim is to investigate the problem of obtaining upper bounds for T2(2), T2(3), T3(2) and T3(1), which are special cases of the symmetric Toeplitz determinant for functions belonging to the M(A, n) subclass. Keyword: convex function; hankel determinant; starlike function; toeplitz determinant; univalent function

On Subordination Results for Certain Classes of Analytic Functions of Reciprocal Order

Muhammet KAMALİ | Alina RISKULOVA

In this paper, we introduce the subclass S-beta (alpha, lambda) of analytic functions and obtain coefficient inequality for functions belong to this class. Furthermore, we give sufficient conditions for starlikeness of reciprocal order of analytic functions. In the last part, we obtain the subordination results of a new subclass of analytic functions of reciprocal order, which are defined here by means of a Hadamard product of analytic functions. The results presented in this work improve or generalize the recent works of other authors and also give rise to several new results.
