In this paper we address the general question of how social influence determines collective outcomes for large populations of individuals faced with binary decisions.

متن کاملDynamics of Collective Decisions in a Time-Dependent Environment
The field of dynamical systems had been revolutionized by the seminal work of Leonid Shil’nikov. As a tribute to his genius we analyze in this paper the response of dynamical systems to systematic variations of a control parameter in time, using a normal form approach. Explicit expressions of the normal forms and of their parameter dependences are derived for a class of systems possessing multi...
