一类二阶线性微分方程的不共轭性与周期解

Disconjugacy of a second order linear differential equation and periodic solutions

V. Ya. Derr

摘要:

本文给出了二阶线性微分方程不共轭的一个新的判别准则。与大多数经典的充分条件不共轭,我们的标准不涉及假设的系数的小方程。我们将这个判据与几个已知的不共轭判据进行了比较,并给出了详细的证明,讨论了不共轭性质在线性常微分算子的因子分解问题和广义Rolle定理证明中的应用.本文是一篇完整的文章,可作为二阶线性微分方程不共轭性理论的一个简要介绍。

英文摘要:

The present paper is devoted to a new criterion for disconjugacy of a second order linear differential equation. Unlike most of the classical sufficient conditions for disconjugacy, our criterion does not involve assumptions on the smallness of the coefficients of the equation. We compare our criterion with several known criteria for disconjugacy, for which we provide detailed proofs, and discuss the applications of the property of disconjugacy to the problem of factorization of linear ordinary differential operators, and to the proof of the generalized Rolle's theorem. The paper is self-contained, and may serve as a brief introduction to theory of disconjugacy of a second order linear differential equation.
