Spectral Deformations of Jacobi Operators
We extend recent work concerning isospectral deformations for one-dimensional Schrödinger operators to the case of Jacobi operators. We provide a complete spectral characterization of a new method that constructs isospectral deformations of a given Jacobi operator (Hu)(n) = a(n)u(n + 1) + a(n − 1)u(n − 1) − b(n)u(n). Our technique is connected to Dirichlet data, that is, the spectrum of the ope...
متن کاملIsospectral Deformations of Random Jacobi Operators
We show the integrability of infinite dimensional Hamiltonian systems obtained by making isospectral deformations of random Jacobi operators over an abstract dynamical system. The time 1 map of these so called random Toda flows can be expressed by a QR decomposition.
متن کاملSpectral Deformations of One-dimensional Schrödinger Operators
We provide a complete spectral characterization of a new method of constructing isospectral (in fact, unitary) deformations of general Schrödinger operators H = − d2 dx2 + V in L2(R). Our technique is connected to Dirichlet data, that is, the spectrum of the operator HD on L2((−∞, x0))⊕L2((x0 ,∞)) with a Dirichlet boundary condition at x0. The transformation moves a single eigenvalue of HD and ...
متن کاملLocal Spectral Properties of Reflectionless Jacobi, Cmv, and Schrödinger Operators
We prove that Jacobi, CMV, and Schrödinger operators, which are reflectionless on a homogeneous set E (in the sense of Carleson), under the assumption of a Blaschke-type condition on their discrete spectra accumulating at E, have purely absolutely continuous spectrum on E.
متن کاملSpectral measures of Jacobi operators with random potentials
Let Hω be a self-adjoint Jacobi operator with a potential sequence {ω(n)}n of independently distributed random variables with continuous probability distributions and let μωφ be the corresponding spectral measure generated by Hω and the vector φ. We consider sets A(ω) which are independent of two consecutive given entries of ω and prove that μωφ(A(ω)) = 0 for almost every ω. This is applied to ...
