In this paper, a probabilistic approach is used to derive a kind of abstract candidate for a natural Lagrangian in general relativity. The methods are very general, and the result is in a certain sense unique. However, to turn this abstract Lagrangian into an ordinary one, expressible in terms of the Riemann tensor, is so far an open problem. Some possible cosmological consequences are discussed.

自然拉格朗日人

在本文中，使用一种概率方法来推导广义相对论中自然拉格朗日的一种抽象候选。这些方法非常通用，从某种意义上讲，结果是独特的。但是，要将这种抽象的拉格朗日化成普通的，用黎曼张量表示，是一个开放的问题。讨论了一些可能的宇宙学后果。
