On mean-field super-brownian motions
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. … Webimmortal Brownian diffusion (with drift) along the path of which independent copies of the original branching Brownian motion immigrate at times which form a Poisson process. Until recently such a spine decomposition for superdiffusions was only available in the literature in a weak form; meaning that it takes the form of a semi-group ...

A stochastic partial differential equation (SPDE) is derived for super-Brownian motion regarded as a distribution function valued process. The strong uniqueness for the solution to this SPDE is obtained by an extended Yamada–Watanabe argument. Similar results are also proved for the Fleming–Viot process. bisect at 50 percent blender
