Maclaurin Coefficient Estimates of Bi-Univalent Functions Connected with the q-Derivative

Maclaurin Coefficient Estimates of Bi-Univalent Functions Connected with the q-Derivative

In this paper we introduce a new subclass of the bi-univalent functions defined in the open unit disc and connected with a <i>q</i>-analogue derivative. We find estimates for the first two Taylor-Maclaurin coefficients <inline-formula> <math display="inline"> <se...
