Fekete-Szegö inequality for analytic and bi-univalent functions subordinate to (p, q) −Lucas polynomials
(Işık University Press, 2021)
In this paper, a subclass of analytic and bi-univalent functions by means of (p, q) − Lucas polynomials is introduced. Certain coefficients bounds for functions belonging to this subclass are obtained. Furthermore, the ...
Coeffıcient estimates for bi-univalent ma-minda type functions associated with q-derivative
(Işık University Press, 2021)
In this article, we consider a new subclasses of analytic and bi-univalent functions associated with q-derivative in the open unit disk. We obtain coefficient bounds for the Taylor-Maclaurin coefficients |a2| and |a3| of ...
Certain subclass of Pascu-type bi-starlike functions in parabolic domain
(Işık University Press, 2021)
Estimates on the coefficients |a2| and |a3| are obtained for normalized analytic function f in the open disk with f and its inverse g = f?1 satisfy the condition that zf0(z) + ?z2f00(z)(1 ? ?)f(z) + ?zf0(z) and zg0(z) + ...
On subclasses of m-fold symmetric bi-univalent functions
(Işık University Press, 2021)
In this study, we introduce and investigate two new subclasses of the biunivalent functions which both f(z) and f?1 (z) are m-fold symmetric analytic functions. Among other results, upper bounds for the coefficients |am+1| ...
Initial bounds for certain classes of bi-univalent functions defined by the (p, q)-lucas polynomials
(Işık University Press, 2021)
Our present investigation is motivated essentially by the fact that, in Geometric Function Theory, one can find many interesting and fruitful usages of a wide variety of special functions and special polynomials. The main ...
The Fekete-Szegö problems for a subclass of m-fold symmetric bi-univalent functions
(Işık University Press, 2021)
In this paper, we investigate a new subclass P??? ?m(?, ?) of m-fold symmetric bi-univalent functions. Moreover, for functions of this subclass, we obtain the coefficient estimates of the Taylor-Maclaurin coefficients ...
