摘要：
In this paper, we introduce and investigate three interesting subclass Sigma(v)*(lambda, alpha), Sigma(B)(v)(beta, alpha) and (Sigma) over tilde (v)*(alpha, beta) of meromorphic and bi- univalent functions on Delta = { z epsilon C : vertical bar z vertical bar > 1}, obtain their coe ffi cient estimates. The results presented in this paper generalize the recent work of several earlier authors.
