An upper bound to the second Hankel determinant for pre-starlike functions of order a

SUMMARY

The objective of this paper is to obtain an upper bound to the second Hankel determinant  for the function f and its inverse belonging to the class of pre-starlike functions of order alpha (0 = alpha = 1), using Toeplitz determinants.
