superprocess : ウィキペディア英語版 | superprocess
An -superprocess, , is a stochastic process on that is usually constructed as a special limit of branching diffusion where the branching mechanism is given by its factorial moment generating function: : and the spatial motion of individual particles is given by the -symmetric stable process with infinitesimal generator . The case corresponds to standard Brownian motion and the -superprocess is called the Dawson-Watanabe superprocess or super-Brownian motion. One of the most important properties of superprocesses is that they are intimately connected with certain nonlinear partial differential equations. The simplest such equation is : ==References==
