Hankel inequalities for a subclass of Bi-Univalent functions based on Salagean type q-difference operator

Abstract

In this investigation a new subclass of bi-univalent functions is established that are defined in the open unit disk ∆={Z ∈ ℂ: |Z| <  l} and are endowed with the Sălăgean type q-difference operator. Then, Hankel inequalities for the new function class are obtained and several related consequences of the results are also stated.
