Coefficient estimates for Ruscheweyh derivatives.
The objective of this paper is to obtain sharp upper bound for the function for the second Hankel determinant , when it belongs to the class of functions whose derivative has a positive real part of order
The objective of this paper is to obtain sharp upper bound to the second Hankel functional associated with the root transform of normalized analytic function belonging to parabolic starlike and uniformly convex functions, defined on the open unit disc in the complex plane, using Toeplitz determinants.
We present some results connected with estimation of the coefficients for some special class of functions holomorphic in the unit disc and defined by subordination to some multivalent functions.
