"Let A be the class of P analytic functions in the unit disc U which are of the form $f(z)=z+\sum_{n=2}^{\infty}a_nz^n$. For 0 ≤ α 0$. We consider the Toeplitz matrices whose elements are the coefficients an of the function f in the class C_α. In this paper we obtain upper bounds for the Toeplitz determinants. "
