Collective behavior based on agent-environment interactions
Gaston Briozzo, Gustavo J. Sibona, Fernando Peruani
We present a model of active particles interacting through a dynamic, heterogeneous environment, leading to emergent collective behaviors without direct agent-to-agent communicatio…

Spreading processes on heterogeneous active systems: spreading threshold, immunization strategies, and vaccination noise
BenjamÃn Marcolongo, Gustavo J. Sibona, Fernando Peruani
We study spreading processes in two-dimensional systems of heterogeneous active agents that exhibit different individual active speeds. We obtain, combining kinetic and complex net…

Resource and population dynamics in an agent-environment interaction model
G. Briozzo, G. J. Sibona, F. Peruani
In any ecosystem, the conditions of the environment and the characteristics of the species that inhabit it are entangled, co-evolving in space and time. We introduce a model that c…
