摘要
研究了一类三阶线性齐次微分方程解的Sturm比较定理的理论,在三阶线性齐次微分方程的Sturm基本定理的基础上得出了Sturm比较定理,所得结论推广了现有文献的相应结果。
In this paper, the Sturm comparison theorem of the third order homogeneous linear equations are researched. On the basis of the Sturm fundamental theorem, the third order homogeneous linear differential equations reaches the Sturm comparison theorem . Some results are generalized.
