On Certain Subclasses of Meromorphic Close-to-Convex Functions [PDF]
Journal of Inequalities and Applications, 2008 By using the operator Dλnf(z), z∈U, Definition 2.1, we introduce a class of meromorphic functions denoted by Σ(α,λ,n) and we obtain certain differential subordinations.

Janowski harmonic close-to-convex functions
International Journal of Mathematical Analysis, 2014 A harmonic mapping in the open unit disc D{double-struck} = {z||z| < 1} onto domain Ω* ⊂ ℂ is a complex valued harmonic function w = f(z) which maps D{double-struck} univalently Ω*. Each such mapping has a canonical representation f(z) = h(z) + g(z), where h(z) and g(z) are analytic in D{double-struck} and h(0) = g(0) = 0, and are called analytic part ...

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.

Properties for Close-to-Convex and Quasi-Convex Functions Using q-Linear Operator [PDF]
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 ...
