Özet

In this work, we use the Faber polynomial expansion by a new method to find upper bounds for vertical bar b(n)vertical bar coefficients for meromorphic bi-univalent functions class Sigma' which is defined by subordination. Further, we generalize and improve some of the previously published results.
