general relativity - EFE and Local Minkowski


Suppose we view the Einstein Field Equations (EFE) in the context of a boundary value problem with a given stress-energy tensor and boundary conditions. The problem is solved by finding a pseudo-metric.


Is there an unspoken condition that the metric to be found is locally Minkowski or is this implied by the EFE?


Specifically, do you get a different resulting pseudo-metric if you choose a different signature such as (+---) rather than (-+++)?

I am studying Statics and saw that: The moment of a force about a given axis (or Torque) is defined by the equation: $M_X = (\vec r \times \...
