摘要:     Wright-Fisher model is an important model in population genetics.  The developments of the Wright-Fisher model provide us various fundamental concepts. A well-known concept is the Poisson-Dirichlet distribution, which has found its many applications in non-parametric Bayesian statistics and physics.  In addition, one direct generalization of the Wright-Fisher model is the Fleming-Viot process, the atomic diffusions of which are the main topic of this talk.

              In this talk, the explicit transition probabilities of the atomic diffusions will be presented. Making use of these transition probabilities, we can obtain the ergodic inequalities of the atomic diffusions.
