A remark on Philos-type oscillation criteria for differential equations
The purpose of this short note is to call attention to expressions of Philos-type criteria for the oscillation of solutions of a simple differential equation. A perfect square expression is used to obtain an evaluation that plays an essential role in the proof of Philos-type oscillation theorems....
