This article defines a new operator called the q-Babalola convolution operator by using
quantum calculus and the convolution of normalized analytic functions in the open unit disk …

In this paper, we find Hankel determinants and coefficient bounds for a subclass of starlike
functions related to Booth lemniscate. In particular, we obtain the first four sharp coefficient …

The purpose of this article is to obtain the sharp estimates of the first four initial logarithmic
coefficients for the class BT s of bounded turning functions associated with a petal-shaped …

The logarithmic coefficients are very essential in the problems of univalent functions theory.
The importance of the logarithmic coefficients is due to the fact that the bounds on …

The main goal of this investigation is to obtain sharp upper bounds for Fekete-Szegö
functional and the third Hankel determinant for a certain subclass SL∗ u, v, α of holomorphic …

In this paper, we introduce three new subclasses of m-fold symmetric holomorphic functions
in the open unit disk U, where the functions f and f− 1 are m-fold symmetric holomorphic …

The object of the present work is to investigate certain new classes of bi-univalent functions
introduced in this paper using the concept of subordination. The research involves a …

In this paper, we introduce and investigate two new subclasses of the function class Σ of bi-
univalent functions of complex order defined in the open unit disk, which are associated with …

On this study, two new subclasses of the function class $\** $ of bi-univalent functions of
complex order defined in the open unit disc are introduced and investigated. These …

In recent years, the Hankel determinant bounds for different subclasses of analytic, starlike
and symmetric starlike functions have been discussed and studied by the many well-known …
