This book provides the basis of a formal language and explores its possibilities in the characterization of multiplex networks. Armed with the formalism developed, the authors define structural metrics for multiplex networks. A methodology to generalize monoplex structural metrics to multiplex networks is also presented so that the reader will be able to generalize other metrics of interest in a systematic way. Therefore, this book will serve as a guide for the theoretical development of new multiplex metrics.
Furthermore, this Brief describes the spectral properties of these networks in relation to concepts from algebraic graph theory and the theory of matrix polynomials. The text is rounded off by analyzing the different structural transitions present in multiplex systems as well as by a brief overview of some representative dynamical processes.
Multiplex Networks will appeal to students, researchers, and professionals within the fields of network science, graph theory, and data science.
Emanuele Cozzo got a degree in Physics and a master degree in Mathematical Physics, both from the University "La Sapienza" Rome. He got its PhD in Physics at the University of Zaragoza, working at the BIFI Institute on multiplex networks structure and dynamics. During is PhD, he has published several seminal papers on multiplex networks. He is now a Postdoc researcher at the University of Barcelona and a member of the University of Barcelona Institute for Complex Systems (UBICS).
Guilherme Ferraz de Arruda got his degree in electrical engineering in 2011 focusing on digital systems and control theory at EESC-University of Sao Paulo, Brazil. He got his master (2013) and Ph.D. (2017) at ICMC-University of Sao Paulo, Brazil, both in complex networks. His Ph.D. thesis is entitled "Modeling spreading processes in complex networks" where he studied spreading processes both in single and multilayer networks. Presently he is a researcher at ISI Foundation.
