Seminario: Collective phenomena in social systems: a statistical physics approach to language competition:
IFISC-CSIC
Día: 10-03-2010
Hora: 12h
Lugar: Seminario de Psicología, 2º piso, Departamento de Psicología, Ed. Guillem Cifre de Colonya, Universidad de las Islas Baleares.
 Resumen: A deep understanding of collective phenomena in Statistical Physics is well established in terms of microscopic models based on the interaction rules among the particles in the system. Partly inspired by this success in linking micro and macro behavior, collective social phenomena are being currently studied in terms of microscopic models of interacting agents. In problems of social dynamics, agents sit in the nodes of a network and change their state (social option) according to specified dynamical rules of interaction with their neighbors in the network. These problems range from opinion dynamics and social dilemmas, to cultural dissemination and language competition.
In this talk and within the general context of models of social consensus, we present a review of the main results obtained in the study of models of language competition in which the role of bilingual agents and network structure are considered in detail. Finally, we argue on the power and limitations of the statistical physics approach to social dynamics. -- |
