Oscillations of a system of delay logistic equations
We obtained sufficient conditions for the oscillation of all positive solutions of the system Ni(t)=Niai−∑j=1mbijNj(t−τ) , i = 1, 2, …, m about its steady state. We also obtained sufficient conditions for the existence of a nonoscillatory solution of this system.
