A Singular Critical Potential For The Schrödinger operator
نویسنده
چکیده
We construct a potential V on R, smooth away from one pole, and a sequence of quasimodes for the operator −∆+V , which concentrate on this pole. No smoothing effect, Strichartz estimates nor dispersive inequalities hold for the corresponding Schrödinger equation.

Note on the spectrum of discrete Schrödinger operators
The spectrum of discrete Schrödinger operator L + V on the d-dimensional lattice is considered, where L denotes the discrete Laplacian and V a delta function with mass at a single point. Eigenvalues of L+V are specified and the absence of singular continuous spectrum is proven. In particular it is shown that an embedded eigenvalue does appear for d ≥ 5 but does not for 1 ≤ d ≤ 4.
متن کاملDiscrete and Embedded Eigenvalues for One-dimensional Schrödinger Operators
I present an example of a discrete Schrödinger operator that shows that it is possible to have embedded singular spectrum and, at the same time, discrete eigenvalues that approach the edges of the essential spectrum (much) faster than exponentially. This settles a conjecture of Simon (in the negative). The potential is of von Neumann-Wigner type, with careful navigation around a previously iden...
متن کاملA Sharp Maximal Function Estimate for Vector-Valued Multilinear Singular Integral Operator
We establish a sharp maximal function estimate for some vector-valued multilinear singular integral operators. As an application, we obtain the $(L^p, L^q)$-norm inequality for vector-valued multilinear operators.
متن کاملp-Adic Schrödinger-Type Operator with Point Interactions
A p-adic Schrödinger-type operator Dα +VY is studied. D α (α > 0) is the operator of fractional differentiation and VY = ∑n i,j=1 bij < δxj , · > δxi (bij ∈ C) is a singular potential containing the Dirac delta functions δx concentrated on a set of points Y = {x1, . . . , xn} of the field of p-adic numbers Qp. It is shown that such a problem is well-posed for α > 1/2 and the singular perturbati...
متن کاملEigenfunction expansion in the singular case for q-Sturm-Liouville operators
In this work, we prove the existence of a spectral function for singular q-Sturm-Liouville operator. Further, we establish a Parseval equality and expansion formula in eigenfunctions by terms of the spectral function.
