On oscillatory behavior of solutions of second order functional differential equations

摘要

The oscillatory and asymptotic behavior of solutions of the functional differential equation (a(t)ψ(x(t))fx183-1(t)) + P(t, x(t), fx183-1(t)) + fx183-2(t, x[g(t)]) = e(t) is discussed. The obtained results extend some of those in the literature.
