Oscillation of neutral differential equations with ”maxima”. (English) Zbl 0836.34076
Summary: In the paper ordinary neutral differential equations with “maxima” $\bigl[ x(t) + p(t) x(t - \tau) \bigr]' + q(t) \max_{[t - \sigma, t]} x(s) = 0$ are considered. Sufficient conditions for oscillation of all solutions are obtained.
