McKean–Vlasov process

In probability theory, a McKean–Vlasov process is a stochastic process described by a stochastic differential equation where the coefficients of the diffusion depend on the distribution of the solution itself.[1][2] The equations are a model for Vlasov equation and were first studied by Henry McKean in 1966.[3]

Definition

McKean–Vlasov processes take the form[3][4]

 

where   describes the law of X and dB denotes the Wiener process. That is the coefficients of the SDE depend on the marginal distribution of the process X. In general, the process can describe non-linear diffusion.[4][5]
