WebC ( u) = ∫ d z e i u z f ( z) = 1 1 + t 2 u 2. This is clearly not a Gaussian as we expect from a Brownian motion. Regarding the scaled random variables I think you have to look at the limit in distribution. The pdf of Z t = B t / t is. g ( z) = t 2 π t e − 1 2 ( z t) 2 t. which goes to zero uniformly as t → ∞.

We study the scaling limit of a branching random walk in static random environment in dimension and show that it is given by a super-Brownian motion in a white noise potential. In dimension we characterize the limit as the unique weak solution to the …
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.
