Toeplitz determinants and positive semidefiniteness

IEEE Transactions on Signal Processing, 1991
The role that the determinants of real, symmetric, Toeplitz matrices play in testing for their positive semidefiniteness is discussed. It is shown that the leading principal minor test is not sufficient in general to test for the positive semidifiniteness of Toepliz matrices, except in certain cases.

On Asymptotics of Toeplitz Determinants with Symbols of Nonstandard Smoothness

Journal of Fourier Analysis and Applications, 2004
Let \(\mathbb T\) denote the unit circle. For a function \(a\in L^1(\mathbb T)\) and an integer \(n\geq 0\), the \(n\)-th Toeplitz determinant \(D_n(a)\) is given by \(D_n(a)=\det(a_{j-k})_{j,k=0}^n\) where \(a_i\) is the \(i\)-th Fourier coefficient of \(a\). In 1952, G. Szegő proved that if \(a\in C^{1+\epsilon}\) and \(a\geq 0\), then \[ \lim_{n\to \

A generalization of Pincus’ formula and Toeplitz operator determinants

Archiv der Mathematik, 2003
The author gives a generalization of Pincus' formula. Let \(H\) be a separable Hilbert space and \({\mathcal C}_1(H)\) the set of all trace class operators on \(H\). The main result contains the following Theorem. Let \(A,B \in {\mathcal L} (H),\) and assume that \(AB-BA\in {\mathcal C}_1(H)\).
