Abstract

In the present paper, two new subclasses of the bi-univalent analytic functions in the open unit disc was dened by convolution. Coefficient bounds involving the Taylor-Maclaurin coefficients ja2j and ja3j of the function f when f is in these classes were considered. The various results, which are presented in this paper, would generalize and improve those in related works of several earlier authors.
