Seminar by Federico Battiston: Structure and dynamics of multiplex networks
Federico Battiston from Queen Mary, University of London will talk about: Title: Structure and dynamics of multiplex networks Abstract: Many real-world complex systems consist of a set of elementary units connected by relationships of different kinds. All such systems are better described in terms of multiplex networks, where the links at each layer represent a …

Paper on Socioeconomic correlations and stratification in social-communication networks
Published in Journal of the Royal Society Interface, 13 125 (2016) Abstract The uneven distribution of wealth and individual economic capacities are among the main forces, which shape modern societies and arguably bias the emerging social structures. However, the study of correlations between the social network and economic status of individuals is difficult due to …

Seminar: The power of local search for clustering by Vincent Viallat Cohen Addad
Abstract : What are the performance guarantees of the algorithms used in practice for clustering problems? In a paper with Phil Klein and Claire Mathieu, we give the first polynomial-time approximation schemes for the following problems: (1) uniform facility location in edge-weighted planar graphs; (2) $k$-median and $k$-means in edge-weighted planar graphs; (3) $k$-means in …

Publication in TCS: On MultiAspect graphs
by Klaus Wehmuth, , Éric Fleury, , Artur Ziviani, http://www.sciencedirect.com/science/article/pii/S0304397516304352 Abstract Different graph generalizations have been recently used in an ad-hoc manner to represent multilayer networks, i.e. systems formed by distinct layers where each layer can be seen as a network. Similar constructions have also been used to represent time-varying networks. We introduce the concept …
