本文通过Pfaffian与射影叶丛研究三阶线性ODE,提出Fuchs-适应模型,将指标多项式嵌入特殊纤维奇点,并赋予Frobenius共振射影几何意义。
AI 中文摘要
我们通过相关的Pfaffian和射影叶丛研究三阶线性微分方程。在正则奇点情形下,我们引入一个Fuchs-适应的Pfaffian模型,其中指标多项式直接出现在特殊纤维奇点方案中,且Frobenius共振获得射影几何解释。
英文摘要
We study third-order linear differential equations through their associated Pfaffian and projective foliations. In the regular-singular setting, we introduce a Fuchs-adapted Pfaffian model in which the indicial polynomial appears directly in the special-fiber singular scheme, and Frobenius resonance acquires a projective geometric interpretation.
