Oscillation theorems for nonlinear second order functional differential equations with damping. (English) Zbl 0595.34069
The authors give sufficient conditions for oscillation of the proper solutions to the functional differential equation
\[
(a(t)\psi (x(t))\dot x(t))^.+p(t)K(t,x(t),\dot x(t))\dot x(t)+q(t)f(x[g(t\quad)])h(\dot x(t))=0.
