Pruning L'evy trees via an admissible family of branching mechanisms
首发时间:2014-04-08
Abstract: By studying an admissible family of branching mechanisms introduced in Li (2014), a pruning procedure on L'evy trees is obtained. Then a decreasing L'evy-CRT-valued process ${T_t}$ by pruning L'evy trees and an analogous process ${T^*_t}$ are constructed by pruning a critical L'evy tree conditioned to be infinite. Under a regular condition on the admissible family of branching mechanisms, it is shown that the law of ${T_t}$ at the ascension time can be represented by ${T^*_t}$. The results generalize those studied in Abraham and Delmas (2012).
