A novel numerical method for mean field stochastic differential equation
Jinhui Zhou, Yongkui Zou, Shimin Chai +2
In this paper, we propose a novel method to approximate the mean field stochastic differential equation by means of approximating the density function via Fokker-Planck equation. W…

Numerical analysis of a time discretized method for nonlinear filtering problem with Lévy process observations
Fengshan Zhang, Yongkui Zou, Shimin Chai +1
In this paper, we consider a nonlinear filtering model with observations driven by correlated Wiener processes and point processes. We first derive a Zakai equation whose solution…
