Sharp estimation of Hermitian-Toeplitz determinants for Janowski type starlike and convex functions
Virendra Kumar; Rekha Srivastava; Nak Eun Cho;Abstract
The sharp upper and lower bounds for the third-order Hermitian-Toeplitz
determinant are investigated for the classes of Janowski type starlike
and convex functions. The results presented in this paper generalize
several recent works in this direction.
