Physics of multilayered interconnected networks

June 2, 2014 ~ Berkeley, California


Most natural and engineered systems include multiple subsystems that are organized as layers of connectivity. It is important to take such features into account to try to improve our understanding of these complex systems. It is thus necessary to generalize "traditional" network theory by developing (and validating) a framework and associated tools to study multilayer systems in a comprehensive fashion and the physical properties that emerge in this new setup. The origins of such efforts date back several decades and arose in multiple disciplines, and now the study of multilayer networks has become one of the most important directions in network science.

Multilayered interconnected networks, and in particular what has been called multiplex networks, explicitly incorporate multiple (and independent) channels of connectivity in a system. They provide a natural description for systems in which entities have a different set of neighbors in each layer (which can represent, e.g., a task, an activity, or a category). A fundamental aspect of describing multiplex networks is defining and quantifying the interconnectivity between different categories of connections. This amounts to switching between layers in a multilayer system, and the associated interlayer connections in a network are responsible for the emergence of new phenomena in multiplex networks. Interlayer connections can generate new structural and dynamical correlations between components of a system, so it is important to develop a framework that takes them into account. The study of these systems is of utmost importance to understand more realistic structured interactions.

Main Conference

NetSci 2014 will take place on Jun 2-6, 2014 in Berkeley California, at the Claremont Hotel and the Clark Kerr Campus of the University of California.


Scope of the satellite meeting

The scope of the satellite meeting is to review the recent advances that have been witnessed in the field of multilayered interconnected networks, focusing in particular on the interplay between structure and dynamics.

The list of topics that we aim to cover at the conference is the following:

  • Empirical measurements of multiplex networks
  • Mathematical properties of multiplex structures
  • Analysis and characterization of multilayer interconnected networks
  • Dynamical processes on interconnected networks
