Continuous-time Discontinuous Equations in Bounded Confidence Opinion Dynamics (1010.0066v4)
Published 1 Oct 2010 in math.OC, cs.SI, cs.SY, and math.DS
Abstract: This report studies a continuous-time version of the well-known Hegselmann-Krause model of opinion dynamics with bounded confidence. As the equations of this model have discontinuous right-hand side, we study their Krasovskii solutions. We present results about existence and completeness of solutions, and asymptotical convergence to equilibria featuring a "clusterization" of opinions. The robustness of such equilibria to small perturbations is also studied.
