Seminario di Probabilità e Finanza Matematica
Mercoledì 3 Luglio 2013 alle ore 16:00 in Aula 2AB45 il Dr. Daniele Regoli dell'Università di Padova terrà un seminario intitolato: "Complex systems with emerging periodic behavior in biological and social sciences".
The need for models that account for periodicity and time synchronization is widespread in natural sciences, such as biology and neurosciences. In social sciences, complex systems of interacting particles which model, for instance, risk contagion in a network of firms have been recently proposed. We provide a very simple toy model -with possible applications both in economics and in biology- of a mean-field stochastic spin system which exhibits an emerging periodic behavior despite of the fact that no periodic force is imposed on the single spins.
