Some Properties of Bazilevič Functions Involving Srivastava–Tomovski Operator
Axioms, 2022 We introduce a new class of Bazilevič functions involving the Srivastava–Tomovski generalization of the Mittag-Leffler function. The family of functions introduced here is superordinated by a conic domain, which is impacted by the Janowski function.

On some geometric properties of normalized Wright functions
Cumhuriyet Science Journal, 2020 The main purpose of the present paper is to determine the radii of lemniscate starlikeness, lemniscate convexity, Janowski starlikeness and Janowski convexity of normalized Wright functions. The key tools in the proof of our main results are the infinite

Some Applications of Analytic Functions Associated with q-Fractional Operator
Mathematics, 2023 This paper introduces a new fractional operator by using the concepts of fractional q-calculus and q-Mittag-Leffler functions. With this fractional operator, Janowski functions are generalized and studied regarding their certain geometric characteristics.

Inclusion of the Generalized Bessel Functions in the Janowski Class [PDF]
International Journal of Analysis, 2016 Sufficient conditions onA,B,p,b, andcare determined that will ensure the generalized Bessel functionup,b,csatisfies the subordinationup,b,c(z)≺1+Az/(1+Bz). In particular this gives conditions for(-4κ/c)(up,b,c(z)-1),c≠0, to be close-to-convex. Also, conditions forup,b,c(z)to be Janowski convex andzup,b,c(z)to be Janowski starlike in the unit diskD=z∈C ...

Class of Analytic Function Related with Uniformly Convex and Janowski’s Functions [PDF]
Journal of Function Spaces, 2018 In this paper, we introduce a new subclass of analytic functions in open unit disc. We obtain coefficient estimates, extreme points, and distortion theorem. We also derived the radii of close-to-convexity and starlikeness for this class.

A Subclass of Meromorphic Close-to-Convex Functions of Janowski's Type [PDF]
International Journal of Mathematics and Mathematical Sciences, 2012 Summary: We introduce a subclass \(\Sigma (A, B)\) (\(-1 \leq B < A \leq 1\)) of functions which are analytic in the punctured unit disk and meromorphically close-to-convex. We obtain some coefficients bounds and some argument and convolution properties for functions belonging to this class.
