AI总结:

本文通过因果相关点对的距离确定闵氏空间结构,为因果集理论的主猜想提供支持。

摘要:

Aleksandrov和Zeeman证明了在闵氏空间维度大于2时,点集之间的因果关系决定了闵氏空间结构,仅相差全局共形因子。我们证明在任意维度中,因果相关点对之间的距离决定了空间相关点对之间的距离,从而完全确定点集的闵氏空间结构。这是朝着证明由洛伦兹流形上的泊松过程产生的因果集确定该流形,仅受限于泊松过程强度的近似程度——因果集理论的主猜想的方向迈进的一步。

英文摘要:

Aleksandrov, and then Zeeman, showed that the causal relations among the set of points in a Minkowski space of dimension greater than 2 determine the Minkowski space structure of the set up to a global conformal factor. We show that in any dimension the distances between causally related pairs of points determine the distances between spatially related pairs of points, and thus completely determine the Minkowski space structure of the set. This is a step in the direction of proving that causal sets arising from a Poisson process in a Lorentzian manifold determine that manifold up to the degree of approximation inherent in the intensity of the Poisson process -- the Hauptvermutung of causal set theory.
