Fundamental statistical features and self-similar properties of tagged networks

Gergely Palla, Illes J. Farkas, Peter Pollner +2

We investigate the fundamental statistical features of tagged (or annotated) networks having a rich variety of attributes associated with their nodes. Tags (attributes, annotations…

Centrality properties of directed module members in social networks

Peter Pollner, Gergely Palla, Daniel Abel +4

Several recent studies of complex networks have suggested algorithms for locating network communities, also called modules or clusters, which are mostly defined as groups of nodes…

Evolutionary Prisoner's Dilemma game on the Newman-Watts networks

Jeromos Vukov, György Szabó, Attila Szolnoki

Maintenance of cooperation was studied for a two-strategy evolutionary Prisoner's Dilemma game where the players are located on a one-dimensional chain and their payoff comes from…

Fluctuation scaling in complex systems: Taylor's law and beyond

Zoltan Eisler, Imre Bartos, Janos Kertesz

Complex systems consist of many interacting elements which participate in some dynamical process. The activity of various elements is often different and the fluctuation in the act…

Directed network modules

Gergely Palla, Illes J. Farkas, Peter Pollner +2

A search technique locating network modules, i.e., internally densely connected groups of nodes in directed networks is introduced by extending the Clique Percolation Method origin…

Noise sensitivity of portfolio selection under various risk measures

Imre Kondor, Szilard Pafka, Gabor Nagy

We study the sensitivity to estimation error of portfolios optimized under various risk measures, including variance, absolute deviation, expected shortfall and maximal loss. We in…
