Asymptotic behaviour of the stochastic Lotka-Volterra model. (English) Zbl 1048.92027
Summary: This paper examines the asymptotic behaviour of a stochastic extension of a fundamentally important population process, namely the Lotka-Volterra model. The stochastic version of this process appears to have far more intriguing properties than its deterministic counterpart. Indeed, the fact that a potential deterministic population explosion can be prevented by the presence of even a tiny amount of environmental noise shows the high level of difference which exists between these two representations.
