Spectra of hyperstars on public transportation networks
Eleonora Andreotti
The purpose of this paper is to introduce a model to study structures which are widely present in public transportation networks. We show that, through hypergraphs, one can describ…
Signless Normalized Laplacian for Hypergraphs
Eleonora Andreotti, Raffaella Mulas
The spectral theory of the normalized Laplacian for chemical hypergraphs is further investigated. The signless normalized Laplacian is introduced and it is shown that its spectrum…
Measuring the stability of spectral clustering
Eleonora Andreotti, Dominik Edelmann, Nicola Guglielmi +1
As an indicator of the stability of spectral clustering of an undirected weighted graph into clusters, the th spectral gap of the graph Laplacian is often considered. The $k…
Equivalence between spectral properties of graphs with and without loops
Eleonora Andreotti, Daniel Remondini, Armando Bazzani
In this paper we introduce a spectra preserving relation between graphs with loops and graphs without loops. This relation is achieved in two steps. First, by generalizing spectra…
Graph partitioning using matrix differential equations
Eleonora Andreotti, Dominik Edelmann, Nicola Guglielmi +1
Given a connected undirected weighted graph, we are concerned with problems related to partitioning the graph. First of all we look for the closest disconnected graph (the minimum…
On the multiplicity of Laplacian eigenvalues and Fiedler partitions
Eleonora Andreotti, Armando Bazzani, Daniel Remondini +1
In this paper we study two classes of graphs, the (m,k)-stars and l-dependent graphs, investigating the relation between spectrum characteristics and graph structure: conditions on…
Pulse shape discrimination for GERDA Phase I data
M. Agostini, M. Allardt, E. Andreotti +111
The GERDA experiment located at the LNGS searches for neutrinoless double beta (0νββ) decay of ^{76}Ge using germanium diodes as source and detector. In Phase I of the experiment e…
The background in the neutrinoless double beta decay experiment GERDA
The GERDA collaboration, M. Agostini, M. Allardt +111
The GERmanium Detector Array (GERDA) experiment at the Gran Sasso underground laboratory (LNGS) of INFN is searching for neutrinoless double beta decay of 76Ge. The signature of th…
