Properties of Third-Order Nonlinear Functional Differential Equations with Mixed Arguments

The aim of this paper is to offer sufficient conditions for property (B) and/or the oscillation of the third-order nonlinear functional differential equation with mixed arguments [()[″()]]′=()([()])+()ℎ([()]). Both cases ∫∞−1/()d=∞ and ∫∞−1/()d<∞ are considered. We deduce properties of the studied equations via new comparison theorems. The results obtained essentially improve and complement earlier ones
