AbstractFor a neutral differential equation ẋ(t)−a(t)ẋg(t)+b(t)xh(t)=0,0⩽a(t)<1,b(t)⩾0,g(t)⩽t,h(t)⩽t, a connection between oscillation properties of the differential equation and differential inequalities is established. Explicit nonoscillation and oscillation conditions and a comparison theorem are presented
