报告简介In thistalk we consider a class of continuous-state branching processes withnonadditive branching mechanism. Such a process can be identified as the uniquenonnegative solution to a generalized version of the stochastic differentialequation for a continuous-state branching process that is driven by both aBrownian motion and a spectrally positive compensated Poisson random measure.Based on the joint work in Li, Yang and Zhou (AAP2019+), we discuss theirextinction, explosion and coming down from infinity behaviors.  In addition, we remark on the boundarybehaviors when the associated Levy measure also allows big jumps with infiniteexpectation.
