Upper Bound of Second Hankel Determinants for Certain Subclasses of Bi-univalent Functions Using Subordination

In this paper, we have investigated second Hankel determinants for some subclasses of Ma-Minda bi-univalent functions in the open unit disc Δ. These results also give an upper bound for second Hankel determinant of Ma-Minda bi-starlike and bi-convex functions.
