Abstract: | Summary Various sufficient conditions are obtained which guarantee that all continuable solutions of (1.1) y″+q(t)y′+p(t)f(y)=0 are
oscillatory. No explicit sign assumptions are made on p(t) although certain integral conditions are assumed to hold with regard
to f(y), p(t) and q(t). Examples are given of the form p(t) = λ/tμ + (βsint)/tα, λ, β, μ, α>0.
