Certain Subclasses of Bistarlike and Biconvex Functions Based on Quasi-Subordination
We introduce the unified biunivalent function class defined based on quasi-subordination and obtained the coefficient estimates for Taylor-Maclaurin coefficients and . Several related classes ofExpand

On the Chebyshev polynomial bounds for λ-convex and μ-starlike functions
In this paper, we obtain initial coefficient estimates for a general subclass of univalent functions by using the Chebyshev polynomials and also we find Fekete-Szego inequalities for this class.
Certain Subclasses of k-Uniformly Starlike and Convex Functions of Order α and Type β with Varying Argument Coefficients
In this paper, we define two new subclass of k-uniformly starlike and convex functions of order type with varying argument of coefficients. Further, we obtain coefficient estimates, extreme points,Expand

Initial estimates for certain subclasses of bi-univalent functions with $\kappa-$Fibonacci numbers
In this work, we consider certain class of bi-univalent functions related with shell-like curves related to $\kappa-$Fibonacci numbers. Further, we obtain the estimates of initial Taylor-MaclaurinExpand
