摘要
考虑具有Holling-(n+1)型功能反应的三维离散捕食系统的数学模型,利用不等式的性质获得系统永久持续生存的充分条件,最后利用Brouwer不动点定理得到系统正周期解的存在性.
A Holling-(n+1)type functional response of three-dimensional mathematical model of discrete prey systems is considered.Some snfficient corlditions ensuring the permanece and existence of periodic solation are obtained by using inequlity skill and Brouwer fixed point theorem.sufficient conditions for permanence of the systems are given using the properties of inequalities.
