On mean-field super-brownian motions
WebWe call X super-Brownian motion (SBM). There are a number of other construc-tions possible, involving discrete time, explicit Brownian migration, etc., but any reasonable combination of Brownian or random walk migration and near critical branching will produce the same limit. Super-Brownian motion is the central ex- Web15 de jul. de 2024 · In this paper, we study a new class of equations called mean-field backward stochastic differential equations (BSDEs, for short) driven by fractional Brownian motion with Hurst parameter H > 1/2. First, the existence and uniqueness of this class of BSDEs are obtained. Second, a comparison theorem of the solutions is established. …

Web10 de abr. de 2024 · A weak solution (X, B) can be loosely described as a pair consisting of the stochastic process X and the Brownian motion B satisfying the ISDE. A strong solution is a weak solution (X, B) such that X is a function of the Brownian motion B and the initial starting point x. (See Refs. 11 11. N. WebThe numerical solutions to a non-linear Fractional Fokker–Planck (FFP) equation are studied estimating the generalized diffusion coefficients.
