Boundary Value Problems, Weyl Functions, and Differential Operators

The book under review is a comprehensive treatment of boundary value problems from the unifying point of view of boundary triplets, offering a panoramic view ranging from abstract problems to

Scattering on periodic metric graphs

We consider the Laplacian on a periodic metric graph and obtain its decomposition into a direct fiber integral in terms of the corresponding discrete Laplacian. Eigenfunctions and eigenvalues of the

Spectral Theory of Infinite Quantum Graphs

We investigate quantum graphs with infinitely many vertices and edges without the common restriction on the geometry of the underlying metric graph that there is a positive lower bound on the lengths

Spectral estimates for infinite quantum graphs

We investigate the bottom of the spectra of infinite quantum graphs, i.e., Laplace operators on metric graphs having infinitely many edges and vertices. We introduce a new definition of the

Zero Measure and Singular Continuous Spectra for Quantum Graphs

We introduce a dynamically defined class of unbounded, connected, equilateral metric graphs on which the Kirchhoff Laplacian has zero Lebesgue measure spectrum and a non-trivial singular continuous

Zero Measure and Singular Continuous Spectra for Quantum Graphs

We introduce a dynamically defined class of unbounded, connected, equilateral metric graphs on which the Kirchhoff Laplacian has zero Lebesgue measure spectrum and a non-trivial singular continuous

Eigenfunctions of Laplacians on periodic metric graphs

We consider the Kirchhoff Laplacians on equilateral periodic metric graphs. We present results about spectral properties of these operators: 1) the decomposition of the metric Laplacians into a

Laplacians on infinite graphs: discrete vs continuous

There are two main notions of a Laplacian operator associated with graphs: discrete graph Laplacians and continuous Laplacians on metric graphs (widely known as quantum graphs). Both objects have a

The notion of exterior derivative, differential forms, Dirac and Laplace operators in the discrete and metric case, using a supersymmetric framework is developed, and the (supersymmetric) index of the discrete Dirac operator generalising the standard index formula involving the Euler characteristic of a graph is calculated.

SPECTRA OF SELF-ADJOINT EXTENSIONS AND APPLICATIONS TO SOLVABLE SCHRÖDINGER OPERATORS

We give a self-contained presentation of the theory of self-adjoint extensions using the technique of boundary triples. A description of the spectra of self-adjoint extensions in terms of the

Equilateral quantum graphs and boundary triples

The aim of the present paper is to analyse the spectrum of Laplace and Dirac type operators on metric graphs. In particular, we show for equilateral graphs how the spectrum (up to exceptional

linear operators in hilbert spaces | springerlink abstract. we recall some fundamental notions of the theory of linear operators in hilbert spaces which are required for a rigorous formulation of the

Cantor and Band Spectra for Periodic Quantum Graphs with Magnetic Fields

We provide an exhaustive spectral analysis of the two-dimensional periodic square graph lattice with a magnetic field. We show that the spectrum consists of the Dirichlet eigenvalues of the edges and

The Eigenvalues of the Laplacian on Locally Finite Networks Under Generalized Node Transition

Abstract.We consider the canonical continuous Laplacian on an infinite locally finite network with different edge lengths under natural transition conditions as continuity at the ramification nodes

Spectral theory of operator measures in Hilbert space

In §2 the spaces L2(Σ,H) are described; this is a solution of a problem posed by M. G. Krĕın. In §3 unitary dilations are used to illustrate the techniques of operator measures. In particular, a

The spectrum of the continuous Laplacian on a graph

We study the spectrum of the continuous Laplacian Δ on a countable connected locally finite graph Γ without self-loops, whose edges have suitable positive conductances and are identified with copies
