Lattice Theory and Toeplitz Determinants

, 2018
This is a survey of our recent joint investigations of lattices that are generated by finite Abelian groups. In the case of cyclic groups, the volume of a fundamental domain of such a lattice is a perturbed Toeplitz determinant with a simple Fisher–Hartwig symbol.

Determinant Representations of Sequences: A Survey

Special Matrices, 2014
This is a survey of recent results concerning (integer) matrices whose leading principal minors are well-known sequences such as Fibonacci, Lucas, Jacobsthal and Pell (sub)sequences. There are different ways for constructing such matrices.

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

Special 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 ...

Toeplitz Determinants with One Fisher–Hartwig Singularity

Journal of Functional Analysis, 1997
The authors study the asymptotic behaviour of the Toeplitz determinants \(T_n (c)\) as \(n\) tends to infinity in the case of symbols with one singularity. This symbol has a form \[ c(e^{i\theta} e^{i\theta}) \prod_{r}^R t_{\beta _r}\left( e^{i(\theta-i\theta _r)}\right) u_{\alpha _r}\left( e^{i(\theta-i\theta _r)}\right) \] where \(t_\beta \left (e^{i\
