OSCILLATIONS OF SOLUTIONS TO SYSTEMS OF NONLINEAR INTEGRODIFFERENTIAL EQUATIONS
非线性积分微分方程组解的振动性

In this paper,we establish the conditions under which the system of integrodifferentialEquations cannot have a solution on an intervalT,],such that each of its Components is positive on ,We also present the sufficient conditions for the existence of A solution on an interval ,T>0,of the system such that all its components are positiveOn.
