Abstract

We derive oscillation criteria for general-type neutral differential equations , , where , , , , , and are real numbers, the functions and are nondecreasing in for each fixed , and is periodic and continuous with respect to for each fixed . In certain special cases, the results obtained generalize and improve some existing ones in the literature.
