報告題目：Extinction behaviour for the positive mutually interacting continuous-state population dynamics.
報告摘要：In this talk we consider a system of stochastic differential equations (SDEs) with two-way positive interaction driven by Brownian motions and spectrally positive a-stable random measures. Such SDEs system can be identified as a Lotka-Volterra type population model with positive interaction. We find some close to sharp conditions for the extinction behaviour. This talk is based on a recent joint works with Jie Xiong and Xiaowen Zhou.
