Explicit determinants, inverses and eigenvalues of four band Toeplitz matrices with perturbed rows [PDF]

open access: yesSpecial Matrices, 2019
In this paper, four-band Toeplitz matrices and four-band Hankel matrices of type I and type II with perturbed rows are introduced. Explicit determinants, inverses and eigenvalues for these matrices are derived by using a nice inverse formula of block ...

Asymptotic formulas for Toeplitz determinants [PDF]

open access: yesTransactions of the American Mathematical Society, 1978
The object of this paper is to find an asymptotic formula for determinants of finite dimensional Toeplitz operators generated by a class of functions with singularities. The formula is a generalization of the Strong Szegö Limit Theorem.

Sharp Bounds of Hermitian Toeplitz Determinants for Bounded Turning Functions [PDF]

open access: yesSymmetry
Hermitian Toeplitz determinants are used in multiple disciplines, including functional analysis, applied mathematics, physics, and engineering sciences. We calculate the sharp upper and lower bounds on the fourth-order Hermitian Toeplitz determinant for ...

Bounds for Toeplitz Determinants and Related Inequalities for a New Subclass of Analytic Functions

open access: yesMathematics, 2023
In this article, we use the q-derivative operator and the principle of subordination to define a new subclass of analytic functions related to the q-Ruscheweyh operator.

Relative Szegő Asymptotics for Toeplitz Determinants [PDF]

open access: yesInternational Mathematics Research Notices, 2017
Abstract We study the asymptotic behaviour, as $n \to \infty$, of ratios of Toeplitz determinants $D_n({\rm e}^h {\rm d}\mu)/D_n({\rm d}\mu)$ defined by a measure $\mu$ on the unit circle and a sufficiently smooth function $h$. The approach we follow is based on the theory of orthogonal polynomials.

Toeplitz and Hankel determinants of logarithmic coefficients for r-valent q-starlike and r-valent q-convex functions [PDF]

open access: yesMethodsX
The aim of the present paper is to extend the notions of q-starlikeness and q-convexity to encompass multivalent q-starlikeness and multivalent q-convexity.

Toeplitz Determinants for a Certain Family of Analytic Functions Endowed with Borel Distribution [PDF]

open access: yesSymmetry, 2023
In this work, we derive coefficient bounds for the symmetric Toeplitz matrices T2(2), T2(3), T3(1), and T3(2), which are the known first four determinants for a new family of analytic functions with Borel distribution series in the open unit disk U ...

Hankel and Toeplitz Determinants for q-Starlike Functions Involving a q-Analog Integral Operator and q-Exponential Function

open access: yesJournal of Function Spaces
This article investigates the upper bounds of the second Hankel and Toeplitz determinants for a family of q-starlike functions defined by a q-analog integral operator, which is a more general form of the q-Srivastava-Attiya operator, and the q ...
