DESCRIPTION:Speakers: Jefferson Rubiano Forero (Universidad Nacional DE Co
 lombia)\nThe model proposed by Default\, Neau\, Amblard\, and Weisbuch (DN
 AW) is relevant in sociophysics for studying the phenomenon of opinion for
 mation in social systems composed of agents that interact in a binary mann
 er. Its relevance lies in the fact that\, through the formulation of an op
 inion exchange rule between pairs of agents whose opinion differences are 
 smaller than a bounded confidence threshold (d)\, and which is expressed i
 n terms of a convergence parameter (μ)\, it is possible to reproduce coll
 ective phenomena observed in social systems such as consensus\, fragmentat
 ion\, and polarization. Within the framework of this model\, by establishi
 ng an analogy between a system of social agents and an ideal gas of free p
 articles\, we present a novel thermostatistical study of the opinion forma
 tion phenomenon based on the definition of the following macroscopic varia
 bles: social temperature (Ts)\, social entropy (Ss)\, and social chemical 
 potential (Ps). In particular\, we define Ts as the first absolute moment 
 of the opinions of all agents in the system with respect to the average op
 inion (Op) per agent. Through numerical simulations that systematically ex
 plore the parameter space (d\, μ)\, we first identify the equilibrium sta
 te as the state for which Ss stabilizes and estimate the convergence time 
 as the elapsed time required to reach equilibrium. Subsequently\, we study
  the opinion formation process by analyzing the temporal evolution of the 
 macroscopic variables Op\, Ts\, Ss\, and Ps. In this way\, we observe that
  d can be interpreted as a measure of social tolerance to interact with di
 ffering opinions\, while μ quantifies the degree of mutual influence betw
 een a pair of agents during an interaction.\n\nhttps://fisindico.uniandes.
