IC Colloquium: Fundamental Structures in Temporal Communication Networks

Talk by Sune Lehmann, Technical University of Denmark

Sune Lehmann is a Professor at the Technical University of Denmark, an Adjunct Professor at the Department of Sociology, University of Copenhagen, and the Associate Director of the Center for Social Data Science (SODAS) at the University of Copenhagen. His work focuses on understanding human behavior based on the traces we leave behind when we interact with technology.


In this talk, Sune Lehmann introduce a framework for modeling temporal communication networks and dynamical processes unfolding on such networks. The framework originates from the (new) observation that there is a meaningful division of temporal communication networks into six dynamic classes, where the class of a network is determined by its generating process. In particular, each class is characterized by a fundamental structure: a temporal-topological network motif, which corresponds to the network structure of communication events in that class of network. The fundamental structures constrain network configurations: only certain configurations are possible within a dynamic class. In this way the framework presented here highlights strong constraints on network structures, which simplify analyses and shape network flows. Therefore the fundamental structures hold the potential to impact how we model temporal networks. The ideas behind the framework draw on extensive empirical data collection, specifically the Copenhagen Networks, which he will also discuss in the talk.
