标题： Comments on "Searching for a continuum limit in CDT quantum gravity"

摘要： 为了便于寻找因果动态三角化方法的连续极限，Ambjørn、Coumbe、Gizbert-Studnicki 和 Jurkiewicz 最近报告了根据裸耦合测量格点间距的结果。 尽管这些作者的方法在技术上是可靠的，但他们从分析中得出的结论在很大程度上依赖于某些未明言的假设。 我阐明了这些假设，并且论证了我们目前对因果动态三角化的理解并不必然支持这些假设的合理性。 显示英文摘要

摘要： To facilitate the search for a continuum limit of causal dynamical triangulations, Ambjorn, Coumbe, Gizbert-Studnicki, and Jurkiewicz recently reported measurements of the lattice spacing as a function of the bare couplings. Although these authors' methods are technically sound, the conclusions that they draw from their analyses rest crucially on certain unstated assumptions. I elucidate these assumptions, and I argue that our current understanding of causal dynamical triangulations does not entail their justification.
