Causal motifs and existence of endogenous cascades in directed networks with application to company defaults
Irena Barjašić, Hrvoje Štefančić, Vedrana Pribičević +1
Motivated by the detection of cascades of defaults in economy, we developed a detection framework for an endogenous spreading based on causal motifs we define in this paper. We ass…
Critical field-exponents for secure message-passing in modular networks
Louis M. Shekhtman, Michael M. Danziger, Ivan Bonamassa +4
We study secure message-passing in the presence of multiple adversaries in modular networks. We assume a dominant fraction of nodes in each module have the same vulnerability, i.e.…
Color-avoiding percolation
Sebastian M. Krause, Michael M. Danziger, Vinko Zlatić
Many real world networks have groups of similar nodes which are vulnerable to the same failure or adversary. Nodes can be colored in such a way that colors encode the shared vulner…
Optimal redundancy against disjoint vulnerabilities in networks
Sebastian M. Krause, Michael M. Danziger, Vinko Zlatić
Redundancy is commonly used to guarantee continued functionality in networked systems. However, often many nodes are vulnerable to the same failure or adversary. A "backup" path is…
Extraction of Temporal Networks from Term Co-occurrences in Online Textual Sources
Marko Popović, Hrvoje Štefančić, Borut Sluban +5
A stream of unstructured news can be a valuable source of hidden relations between different entities, such as financial institutions, countries, or persons. We present an approach…
Geometric origin of scaling in large traffic networks
Marko Popović, Hrvoje Štefančić, Vinko Zlatić
Large scale traffic networks are an indispensable part of contemporary human mobility and international trade. Networks of airport travel or cargo ships movements are invaluable fo…
Robustness and Assortativity for Diffusion-like Processes in Scale-free Networks
Gregorio D'Agostino, Antonio Scala, Vinko Zlatić +1
By analysing the diffusive dynamics of epidemics and of distress in complex networks, we study the effect of the assortativity on the robustness of the networks. We first determine…
Networks with arbitrary edge multiplicities
Vinko Zlatic, Diego Garlaschelli, Guido Caldarelli
One of the main characteristics of real-world networks is their large clustering. Clustering is one aspect of a more general but much less studied structural organization of networ…
Hypergraph topological quantities for tagged social networks
Vinko Zlatić, Gourab Ghoshal, Guido Caldarelli
Recent years have witnessed the emergence of a new class of social networks, that require us to move beyond previously employed representations of complex graph structures. A notab…
Random hypergraphs and their applications
Gourab Ghoshal, Vinko Zlatic, Guido Caldarelli +1
In the last few years we have witnessed the emergence, primarily in on-line communities, of new types of social networks that require for their representation more complex graph st…
Model of Wikipedia growth based on information exchange via reciprocal arcs
Vinko Zlatić, Hrvoje Štefančić
We show how reciprocal arcs significantly influence the structural organization of Wikipedias, online encyclopedias. It is shown that random addition of reciprocal arcs in the stat…
Schroedinger-like PageRank equation and localization in the WWW
Nicola Perra, Vinko Zlatic, Alessandro Chessa +3
The WorldWide Web is one of the most important communication systems we use in our everyday life. Despite its central role, the growth and the development of the WWW is not control…
On the rich-club effect in dense and weighted networks
Vinko Zlatic, Ginestra Bianconi, Albert Diaz-Guilera +3
For many complex networks present in nature only a single instance, usually of large size, is available. Any measurement made on this single instance cannot be repeated on differen…
Wikipedias: Collaborative web-based encyclopedias as complex networks
V. Zlatic, M. Bozicevic, H. Stefancic +1
Wikipedia is a popular web-based encyclopedia edited freely and collaboratively by its users. In this paper we present an analysis of Wikipedias in several languages as complex net…
