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| ...
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 ...
