Hi
I just joined the forum and wanted to thank everyone about your informative posts.
I am currently studying the mathematical foundations of the general relativity and may need some help.
My first question:
Is there a way to perturb the fundamental tensor to obtain another metric tensor?
Or, as I guess, once fundamental tensor is found, it is very hard to make slightest changes!?
What I mean is can I perturb gij to say gij + e and still the new perturbation stays a metric?
