Prey-Predator Model with Constant Investment Rate for Prey and Constant Harvesting Rate for Predator under Holling-Ⅳ Functional Response
摘要
Abstract
A prey-predator model with constant investment rate and dense restriction for prey and constant harvesting rate for predator under Holling-Ⅳ functional response was studied.The existence of the positive equilibrium point was discussed by using isoclines shape, and the condition for the existence and the stability of the equilibrium point were analysed.Finally, the nonexistence of the closed orbit was proven by Dulac function.关键词
