Powers of large random unitary matrices and Toeplitz determinants [PDF]
, 2010 We study the limiting behavior of Tr U^(k(n)), where U is an n x n random unitary matrix and k(n)is a natural number that may vary with n in an arbitrary way. Our analysis is based on the connection with Toeplitz determinants. The central observation of

Asymptotic behavior and zero distribution of polynomials orthogonal with respect to Bessel functions [PDF]
, 2015 We consider polynomials P_n orthogonal with respect to the weight J_? on [0,?), where J_? is the Bessel function of order ?. Asheim and Huybrechs considered these polynomials in connection with complex Gaussian quadrature for oscillatory integrals.

High Voltage, Volume 11, Issue 3, Page 725-737, June 2026.ABSTRACT The stability analysis of Line Commutated Converter High Voltage Direct Current (LCC‐HVDC) is of considerable engineering importance. Establishing its analytical mathematical model helps to analyse stability and the factors that affect stability of the system.

Some identities for determinants of structured matrices [PDF]
, 2002 In this paper we establish several relations between the determinants of the following structured matrices: Hankel matrices, symmetric Toeplitz + Hankel matrices and Toeplitz matrices.

Journal of High Energy Physics, 2021 We explore the correspondence between geometric function theory (GFT) and quantum field theory (QFT). The crossing symmetric dispersion relation provides the necessary tool to examine the connection between GFT, QFT, and effective field theories (EFTs ...

Magnetic Resonance in Medicine, Volume 95, Issue 5, Page 2702-2717, May 2026.ABSTRACT Purpose To achieve high resolution (≤ 1 mm isotropic) whole‐brain perfusion imaging at 7 T with next generation ASL pulse sequence, reconstruction algorithm, and MRI hardware. Methods We capitalized on three major innovations: (1) FLASH‐based pseudo‐Continuous ASL (pCASL) sequence with rotated golden‐angle stack‐of‐spirals (rGA‐SoS) sampling; (

Double-scaling limits of Toeplitz determinants and Fisher-Hartwig singularities [PDF]
, 2018 Double-scaling limits of Toeplitz determinants Dn(ft) generated by a set of functions ft ∈ L1 are discussed as both n → ∞ and t → 0 simultaneously, which is currently of great importance in mathematics and in physics. The main focus is on the cases where
