AI总结:

本文在仅要求电导及其倒数具有有限一阶矩的最小条件下,证明了随机电导模型的淬火泛函中心极限定理,解决了开放问题,并引入了一个新的Sobolev不等式作为关键工具。

AI中文摘要:

我们证明了具有遍历平移不变、严格正最近邻电导的随机电导模型的淬火泛函中心极限定理,仅假设电导及其倒数的有限一阶矩。这通过达到临界一阶矩阈值解决了一个开放问题,该阈值对于某类可积性假设是尖锐的。证明的一个关键成分是一个新的Sobolev不等式,该不等式似乎在文献中缺失。

英文摘要:

We prove a quenched functional central limit theorem for the random conductance model with ergodic translation-invariant, strictly positive nearest-neighbor conductances, assuming only finite first moments of the conductances and their inverses. This settles an open problem by reaching the critical first-moment threshold, which is sharp for a certain class of integrability assumptions. A key ingredient of the proof is a new Sobolev inequality that seems to be missing from the literature.
