Abstrakt

Our main purpose is to present some criteria for the permanence and existence of a positive bounded solution of Kolmogorov predator-prey system. Under certain conditions, it is shown that the system is permanent and there exists a solution which is defined on the whole R and whose components are bounded from above and from below by positive constants.
