On the Essential Spectrum of Quantum Graphs

Integral Equations and Operator Theory, 2017
This paper studies the spectral theory of Schrödinger operators which are defined on a metric graph, embedded in \(\mathbb{R}^n\), which has a periodic structure in the sense that it is invariant under translations defined by of a subgroup of \(\mathbb{R}^n\) isomorphic to \(\mathbb{Z}^m\) (i.e. a lattice).

Spectrum and connectivity of graphs

CWI Quarterly, 1996
The author gives three examples of results concerning the connectedness, the connectivity and the thoughness of graphs which follow by considering their spectrum. Using interlacing [see, e.g., \textit{W. H. Haemers}, Eigenvalue techniques in design and graph theory (1980; Zbl 0429.05013)] short proofs of theorems by \textit{A. E. Brouwer} and \textit{D.
