Sharp bounds on the fourth-order Hermitian Toeplitz determinant for starlike functions of order 1/2

In this paper, we prove the sharp bounds on the fourth-order Hermitian Toeplitz deter- minant for starlike functions of order 1/2, which solves a conjecture posed by Cudna et al. [10] for the case q = 4. Mathematics subject classification (2020): 30C55, 30C45.
