Certain classes of analytic functions defined by Hurwitz-Lerch zeta function

Venkateswarlu Bolineni, Thirupathi Reddy Pinninti, Swapna Galla, Shilpa Rompilli Madhuri

Journal of Applied Analysis

2022

Vol. 28, nr 1

73--81

In this work, we introduce and investigate a new class k - ~USs (b, μ, γ, t) of analytic functions in the open unit disk U with negative coefficients. The object of the present paper is to determine coefficient estimates, neighborhoods and partial sums for functions f belonging to this class.

Starlike and convexity properties of q-Bessel-Struve functions

Oraby Karima M., Mansour Zeinab S. I.

Demonstratio Mathematica

2022

Vol. 55, nr 1

61--80

This paper introduces three different normalization associated with the second and third q-Bessel-Struve functions. We use Hadamard factorizations to determine the radii of starlike and convexity of these functions.

Fekete-Szegö problems for certain class of analytic functions associated with quasi-subordination

Sahoo P.

Journal of Mathematics and Applications

2017

Vol. 40

161--170

In this paper, we determine the coefficient estimates and the Fekete-Szegö inequalities for [wzór], the class of analytic and univalent functions associated with quasi-subordination.

The univalence of general integral operator Bazilevič

Pescar V.

Demonstratio Mathematica

2011

Vol. 44, nr 2

253-260

In this paper we define a general integral operator Bazilevič and we obtain sufficient conditions for univalence of this integral operator.

Subordination results and integral means inequalities for generalized k-starlike functions

Dziok J., Murugusundaramoorthy G., Wiśniowska W.

Journal of Mathematics and Applications

2009

Vol. 31

37-49

In the paper, we introduce a generalized class of k-starlike functions associated with Wright generalized hypergeometric functions and obtain the sequential subordination results and integral means inequalities. Some interesting consequences of our results are also pointed out.

Coefficient estimates for certain class of analytic funtions of compelex order and type beta

Aouf M. K., Yamy M. A. Al.

Demonstratio Mathematica

2005

Vol. 38, nr 2

313--322

Let f(x) = z+ sum (for n=k+1 to infinity) belong to the class S(1 - b),beta), b=0,, complex and 0 < beta < 1. In this paper, we determine sharp coefficient estimates for functions of the form f(z)t = zt + sum (for n=t+kan zn to infinity), where t is a positive integer. The results obtained generalize the work of many authors.
