Oscillation and nonoscillation of delay differential equations

  • Hiroshi Onose


Oscillation and nonoscillation theorems are presented for the second order retarded differential equation
$$\left( {r(t)x'(t)} \right)^\prime + f\left( {x(g(t)),t} \right) = 0 \left( {r(t) > 0} \right)$$
. Our aim here is to get more natural shapes of the results of Kusano and Naito [Annali di Matematica pura ed applicata]. This enables us to knowhow work r(t) for the oscillatory properties of (A).
