Monotonic properties of Kneser solutions of second order linear differential equations with delayed argument

In this paper new monotonic properties of nonoscillatory solutions for second order linear functional differential equations with delayed argument y′′(t) = p(t)y(τ (t)) have been established. New properties are used to introduce criteria for elimination of bounded nonoscillatory solutions for studied equations.
