Hankel Determinant of Second Kind for a New Subclass of Analytic Functions Involving Chebyshev Polynomials

In this paper, a new subclass S∗(μ, β, ℘,Un(t)) of univalent functions is defined by using Opoola differential operator involving subordination principle. The upper bounds to the second Hankel determinant denoted by H2(2) for the subclass S∗(μ, β, ℘,Un(t)) is established in connection with Chebyshev polynomials of the second kind and Toeplitz determinants.
