我们研究延迟微分 Painlevé 方程示例中的奇点限制现象,该方程涉及单个自变量的平移和导数。我们根据射流空间之间的映射对我们的结果提出了几何解释,定义了类似于离散系统奇点分析中感兴趣的奇点,以及它们被限制意味着什么。对于三个先前研究的延迟微分 Painlevé 方程的例子,我们描述了所有这些奇点,并表明它们在我们的几何描述意义上受到限制。
We study singularity confinement phenomena in examples of delay-differential Painlevé equations, which involve shifts and derivatives with respect to a single independent variable. We propose a geometric interpretation of our results in terms of mappings between jet spaces, defining certain singularities analogous to those of interest in the singularity analysis of discrete systems, and what it means for them to be confined. For three previously studied examples of delay-differential Painlevé equations, we describe all such singularities and show they are confined in the sense of our geometric description.
