Abstract:
|
In this paper, we consider the evolution of a system composed of two predator-prey deterministic
systems described by Lotka-Volterra equations in random environment. It is proved that under the influence
of telegraph noise, all positive trajectories of such a system always go out from any compact set of int R+
2
with probability one if two rest points of the two systems do not coincide. In case where they have the rest
point in common, the trajectory either leaves from any compact set of int R+
2 or converges to the rest point.
The escape of the trajectories from any compact set means that the system is neither permanent nor
dissipative. ?? 2005 Elsevier Inc. All rights reserved. |
