$N$th order extension of the Wintner-Leighton theorem. (English) Zbl 1030.34030
Summary: Sufficient conditions are given for the existence of oscillatory and nonoscillatory solutions to a class of $n$th-order linear differential equations. These results include an extension of the Wintner-Leighton theorem.
