Spectral Theory of Differential Operators

TL;DR: The spectral theory of operators in a finite-dimensional space first appeared in connection with the description of the frequencies of small vibrations of mechanical systems (see Arnol-d et al. 1985) and when the vibrations of a string are considered, there arises a simple eigenvalue problem for a differential operator as discussed by the authors.
Journal ArticleDOI

Eigenvalue asymptotics for weakly perturbed Dirac and Schrödinger operators with constant magnetic fields of full rank

TL;DR: In this article, it was shown that for any sign-definite, bounded V which tends to zero at infinity, not too fast, there still are an infinite number of eigenvalues near each Landau level.
Journal ArticleDOI

Negative Discrete Spectrum of Perturbed Multivortex Aharonov-Bohm Hamiltonians

TL;DR: The diamagnetic inequality for the Schrodinger operator H (d) 0 in L 2 (Rd), d=2,3, describing a particle moving in a magnetic field generated by finitely or infinitely many Aharonov-Bohm solenoids located at the points of a discrete set in R2, e.g., a lattice, was established in this article.
Journal Article

Eigenvalue clusters of the Landau Hamiltonian in the exterior of a compact domain

TL;DR: In this paper, the Schrodinger operator with a constant magnetic field in the exterior of a compact domain on the plane is considered and the spectrum of this operator consists of clusters of eigenvalues around the Landau levels.
Journal ArticleDOI

On the spectral properties of the perturbed Landau Hamiltonian.

TL;DR: For the Schrodinger and Pauli operators with constant magnetic field, the spectrum is perturbed if a perturbation by a compactly supported magnetic field is performed as discussed by the authors.
