Heterogeneous mean-field analysis of the generalized Lotka-Volterra model on a network
Fabián Aguirre-López
We study the dynamics of the generalized Lotka-Volterra model with a network structure. Performing a high connectivity expansion for graphs, we write down a mean-field dynamical th…
From chambers to echo chambers: Quantifying polarization with a second-neighbor approach applied to Twitter's climate discussion
Blas Kolic, Fabián Aguirre-López, Sergio Hernández-Williams +1
Social media platforms often foster environments where users primarily engage with content that aligns with their existing beliefs, thereby reinforcing their views and limiting exp…
Random features and polynomial rules
Fabián Aguirre-López, Silvio Franz, Mauro Pastore
Random features models play a distinguished role in the theory of deep learning, describing the behavior of neural networks close to their infinite-width limit. In this work, we pr…
Bringing together two paradigms of non-equilibrium: Fragile versus robust aging in driven glassy systems
Diego Tapias, Charles Marteau, Fabián Aguirre-López +1
There are two key paradigms for non-equilibrium dynamics: on the one hand, aging towards an equilibrium state that cannot be reached on reasonable timescales; on the other, externa…
