Superprocess

For the opposite of a subprocess in computing, see Parent process.

In probability theory, a superprocess is a measure-valued stochastic process that is usually constructed as a special limit of near-critical branching diffusions.

Informally, a superprocess can be seen as a branching process where each particle splits and dies at infinite rates, and evolves in a state space E according to a diffusion equation. We follow the rescaled population of particles, seen as a measure on E.
