AI总结:

本文研究了Cartan-Hadamard流形上Lane-Emden系统正径向解的存在性、存在区域维度、渐近行为二分性及有限能量解的刚性结果。

摘要:

我们研究了在Cartan-Hadamard模型流形$\mathbb{M}^n$上提出的Lane-Emden系统的整体定义正径向解的存在性与定性性质。我们证明,对于临界或超临界指数,存在至少一个单参数族的此类解。根据$\mathbb{M}^n$的随机完备性或不完备性,我们证明了存在区域在前者情况下保持一维,而在后者情况下变为二维。接着,我们研究了解在无穷远处的渐近行为,这在随机完备(其中两个分量都被迫消失)和不完备情况之间再次表现出二分行为。最后,我们证明了有限能量解的刚性结果,表明它们存在当且仅当$\mathbb{M}^n$与$\mathbb{R}^n$等距。

英文摘要:

We investigate existence and qualitative properties of globally defined and positive radial solutions of the Lane-Emden system, posed on a Cartan-Hadamard model manifold $ \mathbb{M}^n $. We prove that, for critical or supercritical exponents, there exists at least a one-parameter family of such solutions. Depending on the stochastic completeness or incompleteness of $ \mathbb{M}^n $, we show that the existence region stays one dimensional in the former case, whereas it becomes two dimensional in the latter. Then, we study the asymptotics at infinity of solutions, which again exhibit a dichotomous behavior between the stochastically complete (where both components are forced to vanish) and incomplete cases. Finally, we prove a rigidity result for finite-energy solutions, showing that they exist if and only if $ \mathbb{M}^n $ is isometric to $ \mathbb{R}^n $.
