Abstract :In this paper, we obtain sharp upper bound to the second Hankel determinant for the functions belong to the class of λ- pseudo starlike functions, an interesting sub class of univalent functions defined in the open unit disc E={z:|z|<1}, using Toeplitz determinants.
Keywords : Analytic function, λ pseudo starlike function, upper bound, second Hankel functional, positive real function, Toeplitz determinants
