Zhang, B. G.; Gopalsamy, K. Oscillation and nonoscillation in a nonautonomous delay-logistic equation. (English) Zbl 0648.34078 Q. Appl. Math. 46, No. 2, 267-273 (1988). Sufficient conditions are obtained for the delay-logistic equation \(\dot x(t)=r(t)x(t)[1-x(t-\tau (t))/K]\) to be respectively oscillatory and nonoscillatory.
