Hankel Inequalities for a Subclass of Bi-Univalent Functions based on Salagean type q-Difference Operator

摘要

In this investigation a new subclass of bi-univalent functions is established that is defined in the open unit disk?Δ={ ∈ ?: 1}?and are endowed with the S?l?gean type q -difference operator. Then, Hankel inequalities for the new function class are obtained and several related consequences of the results are also stated.
