Keywords:
neutral differential equations; oscillatory solutions; property $\Cal A$; property $\Cal B$; quasi-derivatives
Summary:
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 $M_n [x(t)-P(t) x(g(t))]+\delta Q(t)q(x(r(t)))=0.$
