(p, q)-Lucas polynomials and their applications to bi-univalent functions
Proyecciones (Antofagasta), 2019 In the present paper, by using the Lp,q,n(x) functions, our methodology intertwine to yield the Theory of Geometric Functions and that of Special Functions, which are usually considered as very different fields. Thus, we aim at introducing a new class of bi-univalent functions defined through the (p, q)-Lucas polynomials.

On a subclass of analytic functions involving harmonic means
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2015 In the present paper, we consider a generalised subclass of analytic functions involving arithmetic, geometric and harmonic means. For this function class we obtain an inclusion result, Fekete-Szegö inequality and coefficient bounds for bi-univalent ...

Bi-Bazilevič functions of complex order involving Ruscheweyh type q-difference operator
Annales Universitatis Paedagogicae Cracoviensis: Studia Mathematica, 2018 In this paper, we define a new subclass of bi-univalent functions involving q-difference operator in the open unit disk. For functions belonging to this class, we obtain estimates on the first two Taylor-Maclaurin coefficients |a2| and |a3|.

Estimates for the Initial Coefficients of Bi-univalent Functions
, 2016 [[abstract]]A bi-univalent function is a univalent function defined on the unit disk for which the inverse function has a univalent extension to the unit disk. The paper of H. M. Srivastava, A. K. Mishra and P.

Journal of Organizational Behavior, EarlyView.ABSTRACT Research has increasingly highlighted the prevalence of emotionally ambivalent experiences for employees at work, with several self‐regulatory benefits emerging. Yet we do not have a full understanding of which work‐related contexts yield generative or maladaptive consequences of emotional ambivalence.

An extremal problem for univalent functions [PDF]
Let S be the class of functions f(z)=z+a2z2 ,… f(0)=0, f′(0)=1 which are regular and univalent in the unit disk |z| x the equation φ′( x)=0 does not have real roots. Since S is a compact class, there exists x . This problem was first proposed by Petru T.

Coefficient Estimates for Subclasses of Bi-Univalent Functions
Journal of Al-Qadisiyah for Computer Science and Mathematics, 2018 In the present paper, we introduce two new subclasses of the class consisting of analytic and bi-univalent functions in the open unit disk . Also, we obtain the estimates on the Taylor-Maclurin coefficients and for functions in these subclasses. We obtain new special cases for our results.
