SOME PROPERTIES OF q CLOSE-TO-CONVEX FUNCTIONS
Hacettepe Journal of Mathematics and Statistics, 2017 Quantum calculus had been used first time by M.E.H.Ismail, E.Merkes and D.Steyr in the theory of univalent functions [5]. In this present paper we examine the subclass of univalent functions which is defined by quantum calculus.

On Janowski Close-to-Convex Functions Associated with Conic Regions
International Journal of Analysis and Applications, 2020 In this work, we introduce and investigate a class of analytic functions which is a subclass of close-to-convex functions of Janowski type and related to conic regions.

ON CHARACTERIZATION OF THE CLASS OF MEROMCRPHIC CLOSE-TO-CONVEX FUNCTIONS
, 1989 본 논문에서는 Close-to-convex 함수족의 특성을 Meromorphic colse-to-convex 함수족에 확장시켜 보인다. Kaplan 의 증명방법을 수정함으로서 주 정리 3.1을 얻는다 . 또한 Meromorphic close-to-convex 함수족에 관한 계수 문제를 연구해 본다.;The aim of this thesis is to extend the characterization of close-to-convex functions

Close-to-convex multivalent functions with respect to weakly starlike functions
, 1972 It is the object of this article to define close-to-convex multivalent functions in terms of weakly starlike multivalent functions. Six classes are defined, and shown to be equal.

Some Companions of Fejér's Inequality for Convex Functions [PDF]
, 2009 In this paper, we establish some companions of Fejér’s inequality for convex functions which generalize the inequalities of Hermite-Hadamard type from 'Two mappings in connection to Hadamard’s inequalities' (Dragomir, 1992) and 'On some refinements of

Properties for Close-to-Convex and Quasi-Convex Functions Using q-Linear Operator
MathematicsIn this work, we describe the q-analogue of a multiplier–Ruscheweyh operator of a specific family of linear operators Iq,ρs(ν,τ), and we obtain findings related to geometric function theory (GFT) by utilizing approaches established through subordination ...
