In this paper, we consider a two color multi-drawing urn model. At each discrete time step, we draw a sample of m balls (m >2), which will be returned to the urn together with a random...
In this paper, we consider an unbalanced urn model with multiple drawing. At each discrete time step n, we draw m balls at random from an urn containing white and blue balls. The...

A Moran process or Moran model is a simple stochastic process used in biology to describe finite populations. The process is named after Patrick Moran, who first proposed the model in...
The simplest example of a fragmentation process is the stick–breaking process,  More precisely, let us consider a stick of unit size and say that after an exponentially distributed time the...
In mathematics and computer science, a random tree is a tree or arborescence that is formed by a stochastic process. Types of random trees include: Uniform spanning tree, a spanning tree of...
