Query: Improved bounds of the third Hankel determinant for classes of univalent
  functions with bounded turning   In this paper we improve the bounds of the third order Hankel determinant for
two classes of univalent functions with bounded turning. The bounds are not
sharp, but the sharp ones are conjectured.
