Talk:Local symmetry

This page is at the moment factually incorrect. It appear to have been created by somebody who didn't have any understanding of what "local symmetry" means in mathematics and physics. I have not attempted to fix this page, since a correct description of local symmetries is fairly complicated; however, I have removed a couple of erroneous references to this page. 66.244.91.174 17:05, 12 February 2007 (UTC)

Are the factual errors still present? It looks more or less correct now, if somewhat opaque, to me.Steve Avery 14:03, 30 October 2007 (UTC)

I agree that definition is not good at all. I've added some examples but we need to work on the introduction. -- þħɥʂıɕıʄʈ^ʝɘɖı 05:01, 1 May 2008 (UTC)

Possible source

Here's a quote. I'm no physicist, but it seems relevant to this article. I don't know how to summarize the text to make it fit -- if it does.

"...a magnetic field, the time dimension, the massive IVBs (Intermediate Vector Bosons) of the weak force, and the gluon field of the strong force, are all local gauge "currents" of matter (field vectors of the forces) which establish and maintain local gauge symmetries. Cold, crystalline atomic matter is the prototypical example of local gauge symmetry established and maintained from global gauge symmetry - light. Light (free electromagnetic energy) is a globally symmetric energy state from which locally asymmetric atomic matter (bound electromagnetic energy) is devolved. The charge neutrality and inertial stasis of cold atomic matter is the evidence of a locally symmetric energy state, involving charge conservation, alternative charge carriers, and inertial forces, which substitute for and replace the global symmetries. In many respects, the local symmetry state is just as invariant and conserved as the global one, and in fact the two regimes are in constant interaction and equilibration (through virtual particles, long-range fields, etc.).

The reason why we have a dual system of global vs local gauge symmetries in physical law and phenomena is because our Universe consists of massive, local energy forms in relative motion (matter), which are derived from light - a massless, non-local (global) energy form in absolute motion. Functionally, the local symmetries are embodied and enforced through the field vectors of the forces. The field vectors translate timeless global symmetries (such as the virtual charges of matter-antimatter particle pairs) into alternative, material, local, temporal forms (such as the real charges of atomic matter). These local charges conserve the invariant magnitude of the original global symmetries through time, until they can be returned (via the action of their associated forces) to their original symmetric form, light (typically via charge-anticharge annihilations)."

Redirect

I had started to take this to WP:AFD with the comment below but on consideration a redirect to Quantum field theory#Gauge freedom which contains a clear discription and references seem more appropriate.

Per conversations on Talk:Local symmetry, the information in this article is incorrect. There have been attempts to fix the article but nothing concrete or Verfiable, working from Wikipedia:Unreferenced articles I attempted to find a reference for the article. The word "Local" is not used in the page Symmetry which gave me some cause for concern. Per google the phrase "Local symmetry" is used often but search did not find any references that allowed me feel confident to use in support of the contents of this article. This seems like it should be a notable subject, but lack of reliable references and the questionably of the content...

Local symmetry is well known and meaningful term in physics. It is not the same as gauge symmetry (which may be local or global). The redirect is flawed. As for the claim that Per conversations on Talk:Local symmetry, the information in this article is incorrect. that is based on a comment from over a year ago, and addressed since then, as the next comment shows.--Michael C.

per WP:V The threshold for inclusion in Wikipedia is verifiability, not truth—meaning, in this context, whether readers are able to check that material added to Wikipedia has already been published by a reliable source, not whether we think it is true. If you would care to restore the article and include references, be all means do so. If you are not familiar with referencing in Wikipedia see Wikipedia:Wikipedia Signpost/2008-02-04/Tutorial. You also mention that there are different types of "local symmetry" those should be addressed as well. Jeepday (talk) 21:28, 7 May 2008 (UTC)

Approximate symmetry

Is this the same as approximate symmetry? If so, can approximate symmetry redirect here? — Preceding unsigned comment added by 75.139.254.117 (talk) 04:00, 1 April 2017 (UTC)
