Critical Lieb-thirring Bounds in Gaps and the Generalized Nevai Conjecture for Finite Gap Jacobi Matrices

چکیده

We prove bounds of the form ∑ e∈I∩σd(H ) dist ( e, σe(H ) )1/2 ≤ L-norm of a perturbation, where I is a gap. Included are gaps in continuum one-dimensional periodic Schrödinger operators and finite gap Jacobi matrices, where we get a generalized Nevai conjecture about an L1-condition implying a Szegő condition. One key is a general new form of the Birman-Schwinger bound in gaps.

Eigenvalue Bounds in the Gaps of Schrödinger Operators and Jacobi Matrices

We consider C = A+B where A is selfadjoint with a gap (a, b) in its spectrum and B is (relatively) compact. We prove a general result allowing B of indefinite sign and apply it to obtain a (δV ) bound for perturbations of suitable periodic Schrödinger operators and a (not quite) Lieb–Thirring bound for perturbations of algebro-geometric almost periodic Jacobi matrices.

Critical Lieb–thirring Bounds for One-dimensional Schrödinger Operators and Jacobi Matrices with Regular Ground States

While Lieb–Thirring [14] developed their bounds for their proof of stability of matter, they realized that power law bounds on eigenvalues were valid in any dimension over a natural range of powers. Their method only worked for powers above the critical lower bound on possible powers. In dimension ν ≥ 3, the critical power is 0 and the resulting inequality is the celebrated CLR bound [3, 13, 16...

Connection between the Lieb–Thirring conjecture for Schrödinger operators and an isoperimetric problem for ovals on the plane

To determine the sharp constants for the one dimensional Lieb– Thirring inequalities with exponent γ ∈ (1/2, 3/2) is still an open problem. According to a conjecture by Lieb and Thirring the sharp constant for these exponents should be attained by potentials having only one bound state. Here we exhibit a connection between the Lieb–Thirring conjecture for γ = 1 and an isporimetric inequality fo...

New Bounds on the Lieb-thirring Constants

are known as Lieb-Thirring bounds and hold true with finite constants Lγ,d if and only if γ ≥ 1/2 for d = 1, γ > 0 for d = 2 and γ ≥ 0 for d ≥ 3. Here and in the following, A± = (|A| ± A)/2 denote the positive and negative parts of a self-adjoint operator A. The case γ > (1 − d/2)+ was shown by Lieb and Thirring in [21]. The critical case γ = 0, d ≥ 3 is known as the Cwikel-Lieb-Rozenblum inequ...

A Blaschke-type condition for analytic functions on finitely connected domains. Applications to complex perturbations of a finite-band selfadjoint operator

This is a sequel of the article by Borichev–Golinskii– Kupin [2] where the authors obtain Blaschke-type conditions for special classes of analytic functions in the unit disk which satisfy certain growth hypotheses. These results were applied to get Lieb–Thirring inequalities for complex compact perturbations of a selfadjoint operator with a simply connected resolvent set. The first result of th...
