Abstract

In the present paper, some new criteria for property A and the oscillation of third order nonlinear delay differential equations of the type � a(t) h b(t)y ' (t) � ' i�' + p(t)f (y(�(t))) = 0.

Highlights

  • We consider the nonlinear third-order delay differential equation a(t) b(t)y′(t) ′ γ+ p(t)f (y(τ (t))) = 0, t ≥ t0. (E)In the sequel, it is always assumed that (H0) γ is the ratio of odd positive integers,(H1) a, b, p ∈ C([t0, ∞), R+), R+ = (0, ∞), Received: February 10, 2016 Published: June 6, 2016 §Correspondence author c 2016 Academic Publications, Ltd. url: www.acadpubl.euJ

  • It is always assumed that (H0) γ is the ratio of odd positive integers, (H1) a, b, p ∈ C([t0, ∞), R+), R+ = (0, ∞), Received: February 10, 2016

  • We state here that all functional inequalities considered in this article are assumed to hold eventually, i.e., they are satisfied for all t large enough
