On linearized oscillations for neutral delay differential equations. (Chinese. English summary) Zbl 0794.34057
Summary: We prove in the paper, under suitable hypotheses, that all solutions of a certain class of nonlinear neutral delay differential equations oscillate if and only if all solutions of an associated linear equation with periodic coefficients oscillate.
