Perturbation series for Jacobi matrices and the quantum Rabi model [PDF]
Opuscula Mathematica, 2021 We investigate eigenvalue perturbations for a class of infinite tridiagonal matrices which define unbounded self-adjoint operators with discrete spectrum.

Green’s matrix from Jacobi-matrix Hamiltonian [PDF]
Journal of Mathematical Physics, 1997 We propose two ways for determining the Green’s matrix for problems admitting Hamiltonians that have infinite symmetric tridiagonal (i.e., Jacobi) matrix form on some basis representation. In addition to the recurrence relation coming from the Jacobi-matrix, the first approach also requires the matrix elements of the Green’s operator between the first ...

Damped Jacobi Methods Based on Two Different Matrices for Signal Detection in Massive MIMO Uplink
Journal of Microwaves, Optoelectronics and Electromagnetic Applications, 2021 For massive multiple-input multiple-output (m-MIMO) uplink, the performances of the linear minimum mean-square error (MMSE) detector are considered near optimal, and they occupy benchmark place for most linear iterative detectors.

Deficiency indices of block Jacobi matrices and Miura transformation
Special Matrices, 2022 We study the infinite Jacobi block matrices under the discrete Miura-type transformations which relate matrix Volterra and Toda lattice systems to each other and the situations when the deficiency indices of the corresponding operators are the same.

Integration of the finite complex Toda lattice with a self-consistent source
Partial Differential Equations in Applied Mathematics, 2023 In the paper, we derive a finite complex Toda lattice with a self-consistent source. We discuss the complete integrability of the constructed systems that is based on the transformation to the spectral data of an associated finite Jacobi matrix.

Generated Image Editing Method Based on Global-Local Jacobi Disentanglement for Machine Learning
Sensors, 2023 Accurate semantic editing of the generated images is extremely important for machine learning and sample enhancement of big data. Aiming at the problem of semantic entanglement in generated image latent space of the StyleGAN2 network, we proposed a ...

Matrix Jacobi biorthogonal polynomials via Riemann–Hilbert problem
Proceedings of the American Mathematical Society, 2023 We consider matrix orthogonal polynomials related to Jacobi type matrices of weights that can be defined in terms of a given matrix Pearson equation. Stating a Riemann–Hilbert problem we can derive first and second order differential-difference relations that these matrix orthogonal polynomials and the second kind functions associated to them verify ...
