Asymptotic Behaviors of Modified Block Toeplitz Determinant [PDF]
Progress of Theoretical Physics, 1990 Some formulas are given for the asymptotic form of NXN modified block Toeplitz determinants for large N. These formulas are useful in obtaining the asymptotic behaviors of the correlation function of two spins of the Ising model on a two-dimensional regular lattice when the two spins are not on an axis.

DETERMINANT COMPUTATIONS FOR SOME CLASSES OF TOEPLITZ-HANKEL MATRICES [PDF]
, 2019 The purpose of this paper is to compute the asymptotics of determinants of finite sections of operators that are trace class perturbations of Toeplitz operators. For example, we consider the asymptotics in the case where the matrices are of the form (a(i-

Milk Yield and Composition Curves During the Postweaning Machine‐Milking Period in Red Deer Hinds
New Zealand Journal of Agricultural Research, Volume 69, Issue 3, June 2026.Deer milk is a dairy product valued for its unique composition and market potential. Research into deer lactation dynamics remains limited. In this study, 4,386 test‐day records from 170 red deer (Cervus elaphus L.) hinds in New Zealand were used to model the milk yield and composition curves using random regression models based on Legendre polynomials.

Mixture‐Based Estimation of Multivariate Data Hypervolume
Statistical Analysis and Data Mining: An ASA Data Science Journal, Volume 19, Issue 3, June 2026.ABSTRACT Estimating the hypervolume occupied by multivariate data is a fundamental problem in statistics and data science, with applications ranging from ecology and machine learning to multi‐objective optimization and Bayesian inference. Traditional approaches rely on geometric approximations, kernel density estimation, or convex‐hull constructions ...

Discrete Toeplitz Determinants and their Applications. [PDF]
, 2014 In this dissertation, we consider the asymptotics of discrete Toeplitz determinants. We find a simple identity which express a discrete Toeplitz determinant as the product of a continuous Toeplitz determinant and a Fredholm determinant, whose kernel only

The determinant and a factorization of a Toeplitz matrix with some type of Horadam numbers entries [PDF]
In this note, we define a symmetric Toeplitz matrix whose entries are from a particular Horadam sequence. We provide the determinant, the inverse and a factorization for such matrices and their special cases.

Homogeneous Poisson Structures on Loop Spaces of Symmetric Spaces
Symmetry, Integrability and Geometry: Methods and Applications, 2008 This paper is a sequel to [Caine A., Pickrell D., Int. Math. Res. Not., to appear, arXiv:0710.4484], where we studied the Hamiltonian systems which arise from the Evens-Lu construction of homogeneous Poisson structures on both compact and noncompact type

Determinants and inverses of perturbed periodic tridiagonal Toeplitz matrices
Advances in Difference Equations, 2019 In this paper, we deal mainly with a class of periodic tridiagonal Toeplitz matrices with perturbed corners. By matrix decomposition with the Sherman–Morrison–Woodbury formula and constructing the corresponding displacement of matrices we derive the ...
