Dynamics of information spread: the phase space of topics on Telegram — •Anastasia Golovin^1,2, Simon Bauer¹, Sebastian Mohr¹, and Viola Priesemann^1,2 — ¹Max Planck for Dynamics and Self-Organisation, Göttingen, Germany — ²Institute for the Dynamics of Complex Systems, University of Göttingen, Germany

The information that is spread on digital platforms shapes public discourse and influences decision-making. In this talk, we explore the dynamics of topics discussed on Telegram, a privacy-oriented messenger that became a hub for misinformation spread during the COVID-19 pandemic. Using transformer-based topic modeling techniques, we map each Telegram channel onto a trajectory in a high-dimensional phase space of topics. Treating these trajectories as a stochastic dynamical system, we identify topic areas that act as attractors, pulling trajectories from their neighborhood, and others that emerge only transiently in response to global events. This approach bridges computational social science and dynamical systems theory, offering a novel perspective on understanding discourse dynamics in communication networks.
