ESTIMATES FOR CERTAIN HOLOMORPHIC FUNCTIONS AT THE BOUNDARY
In this paper, we present some estimates for certain holomorphic function at the boundary of the unit disc. For which is holomorphic in the unit disc such that we estimate a modulus of the second non-tangential derivative of function at the boundary point b with The sharpness of these inequalities is also proved. Moreover, two examples for our results are considered.
