摘要

Taking general Levy jumps into account, a traditional competition system with stochastic perturbation is proposed and investigated. Sufficient conditions for extinction are discussed as well as weak persistence, nonpersistence in the mean and stochastic permanence. In addition, the critical number between weak persistence in the mean and extinction is obtained. Our results demonstrate that, firstly, white noises has no effect on the persistence and extinction; secondly, the general Levy jumps could make permanence vanish as well as happen.
