Stability of singular spectral types under decaying perturbations
نویسندگان
چکیده
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).

Stability of Spectral Types for Jacobi Matrices under Decaying Random Perturbations
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.
متن کاملStability Analysis of Implicit Difference Equations Under Restricted Perturbations
The stability analysis for linear implicit m-th order difference equations is discussed. We allow the leading coefficient coefficient to be singular, i.e., we include the situation that the system does not generate an explicit recursion. A spectral condition for the characterization of asymptotic stability is presented and computable formulas are derived for the real and complex stability radii...
متن کاملAsymptotic behavior near transition fronts for equations of generalized Cahn–Hilliard form
We consider the asymptotic behavior of perturbations of standing wave solutions arising in evolutionary PDE of generalized Cahn–Hilliard form in one space dimension. Such equations are well known to arise in the study of spinodal decomposition, a phenomenon in which the rapid cooling of a homogeneously mixed binary alloy causes separation to occur, resolving the mixture into its two components ...
متن کاملThe stability of the solution of an inverse spectral problem with a singularity
This paper deals with the singular Sturm-Liouville expressions $ ell y = -y''+q(x)y=lambda y $ on a finite interval, where the potential function $q$ is real and has a singularity inside the interval. Using the asymptotic estimates of a spectral fundamental system of solutions of Sturm-Liouville equation, the asymptotic form of the solution of the equation (0.1) and the ...
متن کاملLyapunov Stability of Linear Continuous Singular Systems: an Overview
In this article a detailed overview of Lyapunov stability of linear continuous systems is presented. The conditions for the existence of the solutions for both regular and irregular singular linear systems are introduced. To guarantee an asymptotical stability for linear continuous singular systems and to provide an impulse-free motion of the system, new stability conditions are analyzed. In th...
