Of course there is. I've mentioned just two of the plethora: defining geometry through
a variational problem and the Ricci flow. Of course you snipped it because you could
not deny it.

Obviously you never studied connections defined by minimising the Yang-Mills action.
Ditto for the Ricci flow.

So what else is new.

It doesn't matter - your claim was general: you said that tensors were matrices.

So now you are saying only GR tensors are matrices?

Matrices identified as tensors in differential geometry are nothing but matrices.  Treating them as tensors would never go wrong.  Prove Koobee Wublee's statement wrong.  <shrug>

Ok, than take back the remark "Irrelevant to GR.  <shrug>".

Quoting your own statements that are made out of uneducated ignorance is 
not an asset, Koobee. You're an attention whore and you bicker because 
it's the only social interaction you know, and it's not very becoming.

You do not know enough to do that. All you can do is make mistakes and/or post
nonsense.

Yes. Jan is not the only person who says that; anybody who actually understands 
tensors and matrices would say that, because THAT IS WHAT TENSORS AND MATRICES ARE.

No. The tensor cannot even be defined without specifying the relevant vector 
space (and often its dual space). But the COMPONENTS (those matrices KW is so 
confused about) can only be defined once one specifies A BASIS that spans the 
vector space.

All the matrices identified by GR are mere tables of numbers.  They are indeed just matrices.  Again, treating all tensors of GR as matrices, you will not go wrong.  Prove Koobee Wublee wrong.  <shrug>

So, Tom should be able to prove Koobee Wublee wrong where Koobee Wublee treats all tensors as matrices.  Tom cannot because all matrices identified as tensors in GR are merely nothing but matrices.  <shrug>

This is the problem.  To specify a so-called tensor, the coordinate system must be already defined and shall never be deviated to another.  Yes, in this situation, you can specify any matrices as what is defined by GR.  In another words, the tensors are only valid in their invariant forms under a specific coordinate system and nothing else.  What happens if someone solves the tensor equations?  Well, all solutions must be referenced to the already defined coordinate system and nothing else.  This can only mean each solution of GR represents a unique and independent geometry USING THE ALREADY AGREED UPON COORDINATE SYSTEM AND NOTHING ELSE.  <shrug>

Give the basis thing a break.  Matrices representing tensors such as the metric tensor already means the auto dot product of the basis.  Tom does not understand basic linear algebra.  Tom is only word salad --- a bullshit artist, a con-man, and a liar.  <shrug>

Common error, done by the newbeginners. There is no fields involved 
anywhere, since the nature of the tensor implicitly includes random 
position in space and time. (random as in Random Access Memory, not as in 
stochastic)

Hello Koobee, 
The G is used as quoted from Newton. Einstein wrote in his book, "The Meaning of Relativity" that he copied G from Newton because that is experimental fact. He offered no theory of how weak gravity is, due to basic natural facts. Do you agree about G in relativity? It is not derived.

Yes, that is correct.  <shrug>

Einstein the nitwit, the plagiarist, and the liar is not capable of performing any rudimentary scientific reasoning.  All the shit has come forth from the autistic retards who choose to indulge themselves in the religion of relativity.  Einstein the nitwit, the plagiarist, and the liar becomes the god of relativity, and this god would whisper garbage into the ears of the relativistic morons who worship the religion.  <shrug>

The fudging of G (gravitational constant, not to be confused with [G] the Einstein tensor) is strictly a boundary condition matching where the integration constants after solving the field equations would serve the roles to allow GR to degenerate into Newtonian law of gravity and nothing else.  <shrug>

For example, the Schwarzschild metric, a solution out of an infinite others, in its raw form is:

**  dS^2 = c^2 w (1 + k / r) dt^2 - dr^2 / (1 + k / r) - r^2 dO^2

Where

**  dS = spacetime geometry
**  q, k = constants

It is found that in order for the raw Schwarzschild metric to satisfy Newtonian law of gravity, the integration constants must be of the following.  <shrug>

**  w = 1
**  k = - 2 G M / c^2

You are such an ignoramus. Why not simply switching to another hobby?

Your keyboard got its paste button stuck again.

Garbage is all yours. Point is you have never understood anything here. This is the only
reason, BTW, you are able to post such monumental nonsense all the time. A person
even with a little understanding would know exactly when and where to stop.

> The fudging of G (gravitational constant, not to be confused with [G] the Einstein tensor) 

It's not any "fudging". You are don't know what you are talking about.

> For example, the Schwarzschild metric, a solution out of an infinite others,

There are no "infinite others" - you don't understand the mathematics underlying this
problem. In the spherically symmetric case there can only exist one tensor satisfying the
Einstein equation. It's a theorem in mathematics - I challenge you to find an error in this
theorem.

"raw form"? Why "raw"?

dS is not any "spacetime geometry", that's a sloppy, amateurish talk. ds^2 is the metric tensor 
(that's lower-case "s", the upper-case is traditionally reserved for volume forms, not line 
elements).

Finally one correct statement in your entire post.

The following solution is also a solution to the field equations.  <shrug>

**  dS^2 = c^2 w dt^2 / (1 + k / r) - (1 + k / r) dr^2
         - r^2 (1 + k / r)^2 dO^2

Stupid!  <shrug>

Nonsense!  <shrug>

Wrong!  ds^2 is a scalar, but the metric tensor is a matrix.  Relativistic moron!  <shrug>

This tensor is a pullback of the usual one (meaning, both spacetimes are physically
identical).

You use sloppy terminology that's not used in the trade.

dS is not geometry. I'm sorry I simply cannot do anything about this little factoid.

No, wrong. ds^2 is a symmetric rank-2 covariant tensor.

This phrase has been copyrighted by Maciej. It is your duty to come up with a different one.

Hmmm, the job of the Tensor is to make the transition possible.
