報告摘要：The spectral gap is estimated for some measure-valued processes, which are induced by the intrinsic/extinsic derivatives on the space of finite measures over a Riemannian manifold. These processes are symmetric with respect to the Dirichlet and Gamma distributions arising from population genetics, where in addition to mutations and selections modelized by the Fleming-Viot processes, diffusions of individuals are also included. This talk is based on a joint work with Professor Feng-Yu Wang.
