Abstract: An
oscillation criterion is given for general sublinear ordinary differential
equations of second order of the form where
with
for
and
f is continuously differentiable on with
for
all The
coefficient a is not assumed to be eventually nonnegative and the
oscillation criterion obtained involves the average behavior of the integral of a.
In the special case of the differential equation this
criterion improves a recent oscillation result due to Wong [10].
Keywords and phrases: second order, sublinear, ordinary differential equations, oscillation, weighted averages.
