Necessary and sufficient conditions for the oscillation a third-order differential equation
We show that under certain restrictions the following three conditions are equivalent: The equation $$ y'''+a(t)y''+b(t)y'+c(t)y=f(t) $$ is oscillatory. The equation $$ x'''+a(t)x''+b(t)x'+c(t)x=0 $$ is oscillatory. The second-orde...
