On mean-field super-brownian motions
Web25 de mai. de 2006 · Infinite canonical super-Brownian motion is a natural candidate for the scaling limit of various random branching objects on $$\mathbb{Z}^d$$ when these objects are critical, mean-field and infinite. We prove that ICSBM is the scaling limit of the spread-out oriented percolation incipient infinite cluster above 4 dimensions and of … WebIn this paper, we employ a mean-field linear stability analysis as well as Brownian dynamics simulations to study the effect of thermal motion on the onset of instability. We find that in the absence of electric fields, Brownian motion consistently suppresses instability formation through randomization of particle orientation.

Web2 de mai. de 2024 · The idea in solving this problem is to represent the sum B ( s) + B ( t) as the sum of an increment. That is, B ( s) + B ( t) = 2 B ( s) + B ( t) − B ( s) and since we know incrememnts of a brownian motion are independent, then 2 B ( s) is independent of B ( t) − B ( s). Thus, we can easily get that E [ B ( s) + B ( t)] = 0 & V a r [ B ( s ...

One of the most important properties of superprocesses is that they are intimately connected with certain nonlinear partial differential equations. 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. …
