Abstract: We are interested in comparing the oscillatory and asymptotic properties of the equations $L_n [x(t)-P(t) x(g(t))]+\delta f(t,x(h(t)))=0$ with those of the equations $M_n [x(t)-P(t) x(g(t))]+\delta Q(t)q(x(r(t)))=0.$
Keywords: neutral differential equations, oscillatory (nonoscillatory) solution, property $\Cal A$, property $\Cal B$, quasi-derivatives
Classification (MSC2000): 34K40, 34K25
