摘要
Oscillation and nonoscillation of the second order differential equation with delay depending on the unknown function(r(t)x′(t))′+f(t,x(t),x(▵(t,x(t))))=0in the case when ∫∞ds/r(s)<∞ holds are consider. The results obtained in this paper can be conjugated with the theorems given by Bainov et al. [J. Comput. Appl. Math. 91 (1998) 87–96].
