Existence of Periodic Solution for a Predator-prey System with Feedback Control
Hassell-Varely type predator-prey coincidence degree theorem Lyapunov function global stability
2012/9/24
A Hassell-Varely type predator-prey system with feedback controls is studied. Using the comparison, continuation theorems and coincidence degree theorem, the existence of positive periodic solutions f...
Existence and Uniqueness of the Positive Solution to a Predator-prey Model with Stochastic Perturbation
Itos formula Brownian motion existence and uniqueness
