Abstract
We introduce and study a family of Markov processes on partitions The processes preserve the socalled zmeasures on partitions previously studied in connection with harmonic analysis on the infinite symmetric group We show that the dynamical correlation functions of these processes have determinantal structure and we explicitly compute their correlation kernels We also compute the scaling limits of the kernels in two different regimes The limit kernels describe the asymptotic behavior of large rows and columns of the corresponding random Young diagrams and the behavior of the Young diagrams near the diagonal
