When higher-order interactions matter: reducibility, parsimony, and microscopic organization
Alex Arenas, Federico Battiston, Andrea Gabrielli
The current debate on higher-order interactions raises a fundamental question: when can systems organized through group interactions be faithfully represented within a graph-based…
Exploring Spatial Segregation Induced by Competition Avoidance as Driving Mechanism for Emergent Coexistence in Microbial Communities
Mattia Mattei, Alex Arenas
This study investigates the role of spatial segregation, prompted by competition avoidance, as a key mechanism for emergent coexistence within microbial communities. Recognizing th…
Pattern formation and bifurcation analysis of delay induced fractional-order epidemic spreading on networks
Jiaying Zhou, Yong Ye, Alex Arenas +2
The spontaneous emergence of ordered structures, known as Turing patterns, in complex networks is a phenomenon that holds potential applications across diverse scientific fields, i…
A triadic approximation reveals the role of interaction overlap on the spread of complex contagions on higher-order networks
Giulio Burgio, Sergio Gómez, Alex Arenas
Contagion processes relying on the exposure to multiple sources are prevalent in social systems, and are effectively represented by hypergraphs. In this Letter, we derive a mean-fi…
Emergence of protective behaviour under different risk perceptions to disease spreading
Mozhgan Khanjanianpak, Nahid Azimi-Tafreshi, Alex Arenas +1
The behaviour of individuals is a main actor in the control of the spread of a communicable disease and, in turn, the spread of an infectious disease can trigger behavioural change…
The impact of homophily on digital proximity tracing
Giulio Burgio, Benjamin Steinegger, Giacomo Rapisardi +1
We study how homophily of human physical interactions affects the efficacy of digital proximity tracing. Analytical results show a non monotonous dependence of the reproduction num…
