✦ Synopsis

Ž X . X New oscillation criteria are established for the equation py q qy s 0 that are different from most known ones in the sense that they are based on the informaw . tion only on a sequence of subintervals of t , ϱ , rather than on the whole 0 half-line. Our results are more natural according to the Sturm Separation Theorem and sharper than some previous results, and can be applied to extreme cases such ϱ Ž . as H q t dt s yϱ.
