Social Force in Pedestrian Crowd
Peng Wang, Xiaoda Wang
This paper provides a new perspective to understand existing controversy on the social force model. These issues include that the social force disobeys Newton 3rd Law, oscillation…
Diffusion and memory effect in a stochastic processes and the correspondence to an information propagation in a social system
Peng Wang, Feng-Chun Pan, Jie Huo +1
A generalized Langevin equation is suggested to describe a system with memory() as well as with positive and negative damping. The equation can…
Non-equilibrium diffusion characteristics of a particle system and the correspondence to a social system
Peng Wang, Feng-Chun Pan, Jie Huo +1
A Langevin equation is suggested to describe a system driven by correlated Gaussian white noise as well as with positive and negative damping demarcated by a critical velocity. The…
Studying on Opinion Evolution by Hamilton-Jacobi Equation
Chen-Jie Feng, Peng Wang, Jie Huo +2
A physical description of an opinion evolution is conducted based on the Hamilton-Jacobi equation derived from a generalized potential and the corresponding Langevin equation. The…
