On generalized close-to-convexity related with strongly Janowski functions [PDF]
, 2023 Janowski functions of strongly type are used to define certain classes of analytic functions which generalize the concept of close-to-convexity and bounded boundary rotation.

Fekete-Szegö functional for a class of non-Bazilevic functions related to quasi-subordination
Demonstratio Mathematica, 2023 In this article, we study the Fekete-Szegö functional associated with a new class of analytic functions related to the class of bounded turning by using the principle of quasi-subordination.

On the order of convolution consistence of certain classes of harmonic functions with varying arguments [PDF]
, 2023 Making use of a modified Hadamard product or convolution of harmonic functions with varying arguments, combined with an integral operator, we study when these functions belong to a given class. Following an idea of U. Bednarz and J.

Extreme points and support points of conformal mappings
Open Mathematics, 2019 There are three types of results in this paper. The first, extending a representation theorem on a conformal mapping that omits two values of equal modulus. This was due to Brickman and Wilken.

On some classes of holomorphic functions whose derivatives have positive real part [PDF]
, 2022 In this paper we discuss about normalized holomorphic functions whose derivatives have positive real part. For this class of functions, denoted R, we present a general distortion result (some upper bounds for the modulus of the k- th derivative of a ...
