How Influencers and Multipliers Drive Polarization and Issue Alignment on Twitter/X
Armin Pournaki, Felix Gaisbauer, Eckehard Olbrich
We investigate the polarization of the German Twittersphere by extracting the main issues discussed and the signaled opinions of users towards those issues based on (re)tweets conc…
A dynamical model of platform choice and online segregation
Sven Banisch, Dennis Jacob, Tom Willaert +1
In order to truly understand how social media might shape online discourses or contribute to societal polarization, we need refined models of platform choice, that is: models that…
Quantifying synergy and redundancy in multiplex networks
Andrea I. Luppi, Eckehard Olbrich, Conor Finn +4
Understanding how different networks relate to each other is key for obtaining a greater insight into complex systems. Here, we introduce an intuitive yet powerful framework to cha…
Order-disorder transition in the zero-temperature Ising model on random graphs
Armin Pournaki, Eckehard Olbrich, Sven Banisch +1
The zero-temperature Ising model is known to reach a fully ordered ground state in sufficiently dense random graphs. In sparse random graphs, the dynamics gets absorbed in disorder…
Continuity and Additivity Properties of Information Decompositions
Johannes Rauh, Pradeep Kr. Banerjee, Eckehard Olbrich +2
Information decompositions quantify how the Shannon information about a given random variable is distributed among several other random variables. Various requirements have been pr…
Grounding force-directed network layouts with latent space models
Felix Gaisbauer, Armin Pournaki, Sven Banisch +1
Force-directed layout algorithms are ubiquitously-used tools for network visualisation across a multitude of scientific disciplines. However, they lack theoretical grounding which…
