Thanks AB for your appreciations. Let me point out just one more thing:
In the equivalent equation only survive derivatives of the logarithm of the scalar-density. This really stands for the ration between two densities which returns a scalar function, so the Jacobian won't show up at all...
The Lagrangian is a scalar-density and by multiplying or dividing it by any scalar function another scalar-density is obtained. There is not physical assumption taken here:
.\ \ \ \ \ \ L=(L / \Lambda).\Lambda=\sigma.\Lambda=\sigma.(L / \sigma )
Yes, you are right, the choice of density...
What may be confussing is the \mathop{q}\limits_{(x)} which I used for representing dynamic variables. The (x) lower-index is used for referencing many of them, nothing to do with coordinates.
The Lagrangian function L(\mathop{q}\limits_{(x)} ,\partial _{\bullet } \mathop{q}\limits_{(x)} ) on a field theory's action-integral is a generally covariant scalar-density so the resulting field equations obtained by using the standard Lagrange's expresions will inevitably involve...
Well, I'm sorry if I bodered someone, I was not complaining just trying to understand.
And you are right, I have seen that those are the usual rights granted to authors after the copyright is transferred to the publishers.
This thread started because for someone like me not having a support...
Is that a standard procedure on people doing research?
I understand that if during the revision the author does not agree with the publisher and/or reviewers on demanded corrections he has the right to change his opinion and decide not to publish with them. Then no copyright transfer should...
On every journal the situation seems to be the same: the copyright-transfer form should be ready and the transfer will be done automatically when the article is accepted for publication. It's not being told explicitly but one can figures out that without the form being signed previously by the...
I'm a bit lost here. Are these journals offering the revision service without conditions? Or they state that once they give you the "ok" for publishing then you will have to release the copyright on previous agreement and do the publication only through their service?
May be I'm missing...
Since I want to keep the copyright then my only choice is to grant a free access to the article.
That may be done by submitting to arXiv but there is the endorsement little problem: I don’t know anyone to whom I can ask to endorse my work and in their service documentation they don’t give a...
I do appreciate your intention on spending time for giving a qualified opinion on the paper.
I also find myself in the dilemma of being required to pay for getting access to many articles without having a clue on what is inside apart for what can be seen in the abstract, so from my point of...
Yes, as any publishing service does. Is there any other way?
As I mentioned earlier my first thought was about this article being interesting mainly to university's physics departments and to research groups working on related subjects. Those who have a budget for getting access to this...
Well, if I were linving in the United States that wouldn't be a problem.
I have checked that kind of material in the local university's library and there is not as much and as actualized as in the Internet.
To make it simple, I'm don't have a supported budget for buying many related articles I would have consulted during my research so it’s a good idea I can use the income from this publication to gain access to them or other related ones. Remember mine is a self-supported stand alone work. Also as...
