Abstract The main objective of the present paper is to define a class q q -starlike functions with respect symmetric points in circular domain. Some interesting results these have been evaluated this article. sufficiency criteria form convolutions are evaluated. Furthermore, other geometric properties such as coefficie...

The logarithmic coefficients play an important role for different estimates in the theory of univalent functions.Due to significance recent studies about coefficients, problem obtaining sharp bounds second Hankel determinant these that is $H_{2,1}(F_f/2)$ was paid attention. We recall if $f$ and $F$ are two analytic functions $\mathbb{D}$, function subordinate $F$, written $f(z)\prec F(z)$, the...

In this paper, we introduce some classes of univalent harmonic functions with respect to the symmetric conjugate points by means subordination, analytic parts which are reciprocal starlike (or convex) functions. Further, combining graph function, discuss bound Bloch constant and norm pre-Schwarzian derivative for classes.

In this paper, we introduce some classes of univalent harmonic functions with respect to the symmetric conjugate points by means subordination, analytic parts which are reciprocal starlike (or convex) functions. Further, discuss geometric properties classes, such as integral expression, coefficient estimation, distortion theorem, Jacobian growth estimates, and covering theorem.

In this study, we familiarise a novel class of Janowski-type star-like functions complex order with regard to j , k -symmetric points based on quantum calculus by subordinating pedal-shaped regions. We found integral representation th...
