Abstract:
Oscillation criteria are given for the second order sublinear
non-autonomous differential equation.
(r(t) (x)x′(t))′ + q(t)g(x(t)) = (t).
These criteria extends and improves earlier oscillation criteria of Kamenev,
Kura, Philos and Wong. Oscillation criteria are also given for second order
sublinear damped non-autonomous differential equations.
