Oscillation of second-order nonlinear differential equations with damping term

We present new oscillation criteria for the second order nonlinear differential equation with damping term of the form \begin{equation*} \left( r(t)\psi (x)f(\dot{x})\right) ^{\cdot }+p(t)\varphi \left(g(x),r(t)\psi(x)f(\dot{x})\right)+q(t)g(x)=0, \end{equation*} where $p$, $q$, $r:[t_{o},\infty )\r...
