Oscillation of nonlinear functional differential equations of the second order Original Research Article

In this paper, we consider the oscillation and nonoscillation of solutions of the second order nonlinear functional differential equation View the MathML source , where α > 0 is a constant, q(t) ∈ C([t0,∞): (0,∞)), f(y) ∈ C(R;R), g′(t) > 0 on [t0, ∞), and limt→∞g(t) = ∞.
