讲座内容：

In this talk we explore multinomial and r-variants of several classic objects in combinatorial probability and branching processes, including random recursive trees, Hoppe trees, random set partitions and compositions. Just as classical combinatorial numbers, such as Stirling, Eulerian, and Lah numbers, play a key role in characterizing the distributions of these processes, their r-analogues also emerge naturally in the exact distributional formulas for the multinomial and r-variants. The talk is based on a recent joint work with Z. Kabluchko (Münster), A. Iksanov (Kyiv) and V. Wachtel (Bielefeld).
