Identification of initial Taylor-Maclaurin coefficients for generalized subclasses of bi-univalent functions

A Akgul - Sahand Communications in Mathematical Analysis, 2018 - scma.maragheh.ac.ir
In the present work, the author determines some coefficient bounds for functions in a new
class of analytic and bi-univalent functions, which are introduced by using of polylogarithmic …

Coefficient Bounds For Subclass of m-fold Symmetric Bi-Univalent Functions Sense of Yamakawa

S Siregar, MNM Pauzi, M Darus - Journal of Physics …, 2019 - search.proquest.com
In this paper we introduce a new subclass\({A} _ {\Sigma, m}^{\alpha}\) of the bi-univalent
function sense of Yamakawa in which both f and f–1 are m-fold symmetric analytic functions …
