AVVISO DI SEMINARIO AL GSSI - L'Aquila

Giovedi 12 dicembre prossimo alle ore 16 presso il Gran Sasso Science Institute il *Prof. Paolo Dai Prà* terrà un seminario dal titolo:

*Strategic interaction in trend-driven dynamics*

*Abstract*: We propose a stochastic dynamics in which N agents update their state simultaneously but not independently. At each time step agents aim at maximizing their individual payoff, depending on their action, on the global trend of the system and on a random noise. In the limit of infinitely many agents, a law of large numbers is obtained; the limit dynamics consist in an implicit dynamical system, possibly multiple valued. For a special model, we determine the phase diagram for the long time behavior of these limit dynamics and we show the existence of a phase, where a locally stable fixed point coexists with a locally stable periodic orbit.
