Estimates for analytic functions concerned with Hankel determinant
UDC 517.5 We give an upper bound of Hankel determinant of the first order $(H_{2}(1))$ for the classes of an analytic function. In addition, an evaluation with the Hankel determinant from below will be given for the second angular derivative of $f(z)$ analytic function. For new inequalities, the res...
