报告题目:Wrong Use of Application of Perfect Square Expression

摘要:The purpose of this talk 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. The required condition is pointed out when using the perfect square expression. To simplify the discussion, here we deal with two second-order linear differential equations, but its content is also applied to a variety of equations.
