Popis:	An oscillation criterion is given for () (ru”)” + (pu′)′ + qu = 0, where p is “small” in the sense that () (rv′)′ + pv = 0 is nonoscillatory. If we further restrict p to ensure that () has bounded nonoscillatory solutions, then a known oscillation criterion for (ru”)” + qu = 0 ensures oscillation for ().
