二值噪声诱导下Holling Ⅳ-Leslie捕食系统不稳定性研究
Instability of Holling Ⅳ-Leslie predator-prey system induced by dichotomous noise
摘要
Abstract
In the report,the stability regulation mechanism of the Holling Ⅳ-Leslie predator-prey system under dichotomous noise was investigated.By characterizing the critical bifurcation conditions that lead to the instability induced by dichotomous noise,the effects of the noise intensity and the temporal memory on the system's stability were analyzed,and it was demonstrated that adjusting temporal memory can expand the region of Turing instability more sensitively.The numerical simulation experiment results indicated that dichotomous noise destabilizes the system by reshaping bifurcation curves and inducing limit cycle oscillations.关键词
