Second Hankel determinant for bounded turning functions of order beta of certain subclasses of analytic functions

Let U(β, γ, t) denote the generalized class of normalized analytic univalent functions the unit disk, E = Z:|Z|<1 and satisfy where and z ∈ E. In this paper, we have found upper bound of second Hankel determinant, for f U (β, γ, t). © Published under licence by IOP Publishing Ltd.
