Oscillation of two-dimensional linear second-order differential systems
The authors discuss oscillatory behaviour of solutions of a system of second order linear differential equations, verifying and improving a conjecture of \textit{D. Hinton} and \textit{R. T. Lewis} [Rocky Mt. J. Math. 10, 751-766 (1980; Zbl 0485.34021)].
