Are the equations of relativity closed

  1. Are the equations of relativity "closed"

    Are the equations of relativity "closed" i mean if we can add an extra term of 0 covariant derivative to them without alter thes olution i mean if we have the equations

    Gab=Tab , will the equations

    Gab+Uab=Tab with DUab=0 (covariant derivative)


    can both equation provide the same geometrical interpretation of gravity?...

    The cosmological constant is essentially just that.

    Re: Relativity

    Can you rephrase this question? You write

    ".., will the equations (..) can both provide the same geometrical interpretation of gravity."

    I don't know what this means. They clearly have different solutions.
