Properties of a Linear Operator Involving Lambert Series and Rabotnov Function
International Journal of Mathematics and Mathematical Sciences, Volume 2024, Issue 1, 2024.This work is an attempt to apply Lambert series in the theory of univalent functions. We first consider the Hadamard product of Rabotnov function and Lambert series with coefficients derived from the arithmetic function σ(n) to introduce a normalized linear operator JRα,βz.

Univalence of a New General Integral Operator Associated with the q-Hypergeometric Function
International Journal of Mathematics and Mathematical Sciences, 2013 Motivated by the familiar q-hypergeometric functions, we introduce a new family of integral operators and obtain new sufficient conditions of univalence criteria. Several corollaries and consequences of the main results are also pointed out.

A New Method for Estimating General Coefficients to Classes of Bi‐univalent Functions
Journal of Function Spaces, Volume 2024, Issue 1, 2024.This study establishes a new method to investigate bounds of |ak|; (k ≥ n), for certain general classes of bi‐univalent functions. The results include a number of improvements and generalizations for well‐known estimations. We also discuss bounds of nan2−a21n− and consider several corollaries, remarks, and consequences of the results presented in this ...

On Univalence Criteria for a General Integral Operator
Journal of Function Spaces and Applications, 2012 We consider a new general integral operator, and we give sufficient conditions for the univalence of this integral operator in the open unit disk of the complex plane. Several consequences of the main results are also shown.

Some criteria for two new integral operators [PDF]
Surveys in Mathematics and its Applications, 2012 Using the Hadamard product, we define two new integral operators. The main object of the present paper is to discuss some univalence conditions for these operators. Several corollaries of the main results are also considered.

Properties of a new integral operator
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2016 In this paper, we derive sufficient conditions for the univalence, star- likeness, convexity and some other properties in the class N (ρ) ; for a new integral operator defined on the space of normalized analytic functions in the open unit disk.

ON PROBLEMS OF UNIVALENCE FOR THE CLASS TR(1/2)
Проблемы анализа, 2007 In this paper we discuss the class TR(1/2) consisted of typically real functions given by the integral formula. The problems of local univalence, univalence, convexity in the direction of real and imaginary axes are examined.
