Estimating coefficients for subclasses of meromorphic bi-univalent functions associated with linear operator

Abstract

In this paper we define a differential linear operator, applying it on the subclasses H??B (?, n, ?) of meromorphic starlike bi-univalent functions of order ?, and H?˜ ?B (?, n, ?) of meromorphic strongly starlike bi-univalent functions of order ?, also we find estimates on the coefficients |bo| and |b1| for functions in these subclasses.
