Stability of Spectral Types for Jacobi Matrices under Decaying Random Perturbations
نویسنده
چکیده
We study stability of spectral types for semi-infinite self-adjoint tridiagonal matrices under random decaying perturbations. We show that absolutely continuous spectrum associated with bounded eigenfunctions is stable under Hilbert-Schmidt random perturbations. We also obtain some results for singular spectral types.

Spectral averaging techniques for Jacobi matrices
Spectral averaging techniques for one-dimensional discrete Schrödinger operators are revisited and extended. In particular, simultaneous averaging over several parameters is discussed. Special focus is put on proving lower bounds on the density of the averaged spectral measures. These Wegner type estimates are used to analyze stability properties for the spectral types of Jacobi matrices under ...
متن کاملSpectral and Dynamical Properties of Certain Random Jacobi Matrices with Growing Parameters
Abstract. In this paper, a family of random Jacobi matrices, with off-diagonal terms that exhibit power-law growth, is studied. Since the growth of the randomness is slower than that of these terms, it is possible to use methods applied in the study of Schrödinger operators with random decaying potentials. A particular result of the analysis is the existence of operators with arbitrarily fast t...
متن کاملOn the sensitivity of Lanczos recursions to the spectrum
We obtain novel, explicit formulas for the sensitivity of Jacobi matrices to small perturbations of their spectra. Our derivation is based on the connection between Lanczos’s algorithm and the discrete Gel’fand–Levitan inverse spectral method. We prove uniform stability of Lanczos recursions in discrete primitive norms, for perturbations of the eigenvalues relative to their separations. A stron...
متن کاملStability of singular spectral types under decaying perturbations
We look at invariance of a.e. boundary condition spectral behavior under perturbations, W ; of half-line, continuum or discrete Schrödinger operators. We extend the results of del Rio, Simon, Stolz from compactly supported W ’s to suitable short-range W : We also discuss invariance of the local Hausdorff dimension of spectral measures under such perturbations. r 2002 Elsevier Science (USA).

We study the stability of convergence of the ChristoffelDarboux kernel, associated with a compactly supported measure, to the sine kernel, under perturbations of the Jacobi coefficients of the measure. We prove stability under variations of the boundary conditions and stability in a weak sense under l and random l diagonal perturbations. We also show that convergence to the sine kernel at x imp...
