Hermitian–Toeplitz and Hankel determinants for Sakaguchi-type functions defined by a rational function
UDC 517.5 We obtain the best possible estimates for the Hermitian–Toeplitz determinant of the third order for a class of starlike functions with respect to a symmetric point associated with a rational function. In addition, we determine the upper bounds for the third Hankel determinants.
