Toeplitz Determinants for Inverse of Analytic Functions [PDF]
Estimates bounds for Carathéodory functions in the complex domain are applied to demonstrate sharp limits for the inverse of analytic functions. Determining these values is considered a more difficult task compared to finding the values of analytic ...

Boundary values of Hankel and Toeplitz determinants for q-convex functions [PDF]
The study of holomorphic functions has been recently extended through the application of diverse techniques, among which quantum calculus stands out due to its wide-ranging applications across various scientific disciplines. In this context, we introduce

Toeplitz determinants in one and higher dimensions
In this study, we derive the sharp bounds of certain Toeplitz determinants whose entries are the coefficients of holomorphic functions belonging to a class defined on the unit disk $\mathbb{U}$. Further, these results are extended to a class of holomorphic functions on the unit ball in a complex Banach space and on the unit polydisc in $\mathbb{C}^n ...

Hermitian–Toeplitz determinants for certain univalent functions [PDF]
Sharp upper and lower bounds for the second and third order Hermitian-Toepilitz determinants are obtained for some generalized subclasses of starlike and convex functions. Applications of these results are also discussed for several widely known classes.

Hankel and Symmetric Toeplitz Determinants for a New Subclass of q-Starlike Functions
This paper considers the basic concepts of q-calculus and the principle of subordination. We define a new subclass of q-starlike functions related to the Salagean q-differential operator.

Hankel and Toeplitz determinants for a subclass of analytic functions
Let the function $f\left( z \right) =z+\sum_{k=2}^{\infty}a{_{k}}z {^{k}}\in A$ be locally univalent for $z \in \mathbb{D}% :=\{z \in \mathbb{C}:{|}z {|}

Certain inequalities related with Hankel and Toeplitz determinant for q-starlike functions [PDF]
In the present article, we prove the sharp upper bounds for the second order Hankel determinants |H2(1)|,|H2(2)| and related functionals |a2a3−a4|, |a2a5−a3a4| for q-starlike functions.
