When are two spacetimes the same

  1. Nov 12, 2008 #1
    Suppose you have two spacetimes described by two metrics.

    If I prove that they have foliations with the same geometrical properties, would that prove the spacetimes are actually the same only in different coordinates?

    Has anyone seen a source with theorems of this type?

    The first thing to distinguish is a metric from a coordinate chart. Different coordinate charts can refer to the same metric.
