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.
