Gibbs distributions for random partitions generated by a fragmentation process
In this paper we study random partitions of {1, . . . , n} where every cluster of size j can be in any of wj possible internal states. The Gibbs (n, k, w) distribution is obtained by sampling uniformly among such partitions with k clusters. We provide conditions on the weight sequence w allowing construction of a partition valued random process where at step k the state has the Gibbs (n, k, w) ...

متن کاملCONNECTEDNESS OF GRAPHS GENERATED BY A RANDOM d-PROCESS
Suppose that a graph process begins with n isolated vertices, to which edges are added randomly one by one so that the maximum degree of the induced graph is always at most d . In a previous article, the authors showed that as n → ∞, with probability tending to 1, the result of this process is a d-regular graph. This graph is shown to be connected with probability asymptotic to 1. 2000 Mathemat...
متن کاملOn Secondary Processes Generated by Random Point Distributions
In the paper [3] we have given a rigorous mathematical model and a general method for solving special problems in connection with secondary processes generated by a random point distribution of Poisson type. A random point distribution is a random selection of a finite or countably infinite number of points of an abstract set T where a σ-algebra ST is given. It is supposed that if ξ(A) denotes ...
متن کاملGibbs fragmentation trees
We study fragmentation trees of Gibbs type. In the binary case, we identify the most general Gibbs type fragmentation tree with Aldous’s beta-splitting model, which has an extended parameter range β > −2 with respect to the beta(β + 1, β + 1) probability distributions on which it is based. In the multifurcating case, we show that Gibbs fragmentation trees are associated with the two-parameter P...
