Self-organized collective coordinated behaviour is an impressive phenomenon, observed in
a variety of natural and artificial systems, in which coherent global structures or dynamics …

The increasing interest in complex networks research has been motivated by intrinsic
features of this area, such as the generality of the approach to represent and model virtually …

To capture systemic risk related to network structures, this paper introduces a measure that
complements direct exposures with common exposures, as well as compares these to each …

We study the effects of social influences in opinion dynamics. In particular, we define a
simple model, based on the majority rule voting, in order to consider the role of conformity …

Hyperbolic networks have high clustering, short average path lengths, and community
structure, which are all properties that are commonly associated with social networks. As …

Human history has been marked by social instability and conflict, often driven by the
irreconcilability of opposing sets of beliefs, ideologies, and religious dogmas. The dynamics …

In this study, we analyse the relationship between heterogeneity and cooperation. Previous
investigations suggest that this relation is non-trivial, as some authors found that …

Social connectedness is vital for developing group cohesion and strengthening
belongingness. However, with the accelerating pace of modern life, people have fewer …

The massive diffusion of online social media allows for the rapid and uncontrolled spreading
of conspiracy theories, hoaxes, unsubstantiated claims, and false news. Such an impressive …

In this work, we analyze the hyperbolicity of real-world networks, a geometric quantity that
measures if a space is negatively curved. We provide two improvements in our …
