The Essential Spectrum of the Discrete Laplacian on Klaus-sparse Graphs
Sylvain Golenia, Françoise Truc
In 1983, Klaus studied a class of potentials with bumps and computed the essential spectrum of the associated Schr{ö}dinger operator with the help of some localisations at infinity…
Magnetic Schroedinger operators with radially symmetric magnetic field and radially symmetric electric potential
Diana Barseghyan, Francoise Truc
The aim of the paper is to derive spectral estimates on the eigenvalue moments of the magnetic Schroedinger operators defined on the two-dimensional disk with a radially symmetric…
Magnetic Dirichlet Laplacian with radially symmetric magnetic field
Diana Barseghyan, Francoise Truc
The aim of the paper is to derive spectral estimates on the eigenvalue moments of the magnetic Dirichlet Laplacian defined on the two-dimensional disk with a radially symmetric mag…
Topological Resonances on Quantum Graphs
Yves Colin de Verdìère, Francoise Truc
In this paper, we try to put the results of Smilansky and al. on "Topological resonances" on a mathematical basis.A key role in the asymptotic of resonances near the real axis for…
Self-adjoint extensions of differential operators on Riemannian manifolds
Ognjen Milatovic, Francoise Truc
We study , where is a first order elliptic differential operator acting on sections of a Hermitian vector bundle over a Riemannian manifold , and is a Hermitia…
Schrödinger operators on a half-line with inverse square potentials
Hynek Kovarik, Francoise Truc
We consider Schrôdinger operators given by equation (1.1) below. We study the asymptotic behavior of the spectral density when goes to and the $L^1\to L^\…
