报告摘要： In this talk we consider the systems of two stochastic differential equations (SDEs) with two-way interactions driven by Brownian motions and spectrally positive $\alpha$-stable random measures. Such SDEs system can be identified as a Lotka-Volterra type population models. We find some close to sharp conditions for the extinction behaviours. This talk is based on two recent joint works with Jie Xiong and Xiaowen Zhou.
