Abstract

AbstractFor a sequence of adjacency matrices, describing the unfolding of a network from the graph of a star, through graphs of a broom, to the graph of a link with constant vertices and edges, we ...

Highlights

  • Our study of how the leading eigenvalue, or the spectral radius, of an adjacency matrix of a network varies when the structure of the network changes is motivated by recent interests of research in how an infectious disease spreads over a network (Brauer, 2008; Diekmann & Heesterbeek, 2000; Newman, 2002, 2010)

  • In a network of agents susceptible to an infectious disease, assume that we know all details of the structure of the network: whether and how different agents are connected to each other

Summary

Introduction

Our study of how the leading eigenvalue, or the spectral radius, of an adjacency matrix of a network varies when the structure of the network changes is motivated by recent interests of research in how an infectious disease spreads over a network (Brauer, 2008; Diekmann & Heesterbeek, 2000; Newman, 2002, 2010).
