univalent, Hermitian Toepliz determinant of second order, Hermitian Toepliz determinant of third order, class U, convex functionsAbstract
Introducing a new method, we give sharp estimates of the Hermitian Toeplitz determinants of third order for the class $\mathcal{S}$ of functions univalent in the unit disc. The new approach is also illustrated on some subclasses of the class $\mathcal{S}$.
