Perturbations on the antidiagonals of Hankel matrices [PDF]
Applied Mathematics and Computation, 2013 Given a strongly regular Hankel matrix, and its associated sequence of moments whichdefines a quasi-definite moment linear functional, we study the perturbation of a fixedmoment, i.e., a perturbation of one antidiagonal of the Hankel matrix. We define a linearfunctional whose action results in such a perturbation and establish necessary and ...

Blind image restoration as a convex optimization problem [PDF]
International Journal for Simulation and Multidisciplinary Design Optimization, 2010 In this paper, we consider the blind image restoration as a convex constrained problem and we propose to solve this problem by a conditional gradient ethod. Such a method is based on a Thikonov regularization technique and is obtained by an approximation

Clocking convergence to Arnold tongues – the circle map revisited
Lietuvos Matematikos Rinkinys, 2012 Computational techniques based on ranks of Hankel matrices is used to study the convergence to Arnold tongues. It appears that the process of convergence to the phaselocked mode is far from being trivial.

The Second Hankel Determinant Problem for a Class of Bi-Univalent Functions
Journal of Mathematical and Fundamental Sciences, 2019 Hankel matrices are related to a wide range of disparate determinant computations and algorithms and some very attractive computational properties are allocated to them.

Nonlinear input-normal realizations based on the differential eigenstructure of hankel operators [PDF]
, 2005 This paper investigates the differential eigenstructure of Hankel operators for nonlinear systems. First, it is proven that the variational system and the Hamiltonian extension with extended input and output spaces can be interpreted as the Gâteaux ...

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 ...

On Symmetric Factorizations of Hankel Matrices
2023 IEEE 64th Annual Symposium on Foundations of Computer Science (FOCS), 2023 We present two conjectures regarding the running time of computing symmetric factorizations for a Hankel matrix $\mathbf{H}$ and its inverse $\mathbf{H}^{-1}$ as $\mathbf{B}\mathbf{B}^*$ under fixed-point arithmetic. If solved, these would result in a faster-than-matrix-multiplication algorithm for solving sparse poly-conditioned linear programming ...
