Your above link (I did *not* check your tensor indices) is the reply
you wrote *after* I said you that you were deriving the tensor in a
*wrong* way

Since you aren't going to let this go, I'll just go to the time stamps.

Do you have a different concept of "after" in your universe?

Continue to lye that you will gain a lot of from that.

Before (your mistake being noticed)

After (you negating you did any mistake)

More latter (the correction)

Also have a look to the indices :-)

And it was an obvious mistake which I should not have made. But I did,
and I corrected it.

You didn't provide the correction - you just said it was wrong. Try not
to be too much of a credit hog.

Let us analyze your paranoia. The movie may be.

You -who are a very clever master on physics- wrote a derivative of a
T^ab with a single \Gamma. Just as if you were writing the derivative of
a vector u^a.

I said that you were wrong differentiating T^ab using the vector rule.
But I am an ignorant and I wrote that just after launching a coin.

You -still being the same clever folk- replied

(\blockquote
They don't? A vector is a rank one contravariant tensor.

I took the covariant derivative of the stress energy tensor along one
contravariant slot and took summed on the index to form the
divergence.

Since I am so clearly wrong in your eye, I'd appreciate you writing
the _proper_ expression for taking the divergence of a rank two
tensor.

And then in next message

msg/8ac5d4ef041f1f8a

I said to you how to do and *why*.

In your fantasy, I did learn the formulae from you (that index are
different does not matter for you) and the further explanation on signs
and number of \Gammas I got from a luck cookie obviously.

If this is accurate, let me please because I will add to a new version of
guidelines as example.
