Lagrangian into a DAB page, separate article for Lagrangian field theory[edit]

The scope of this article is too big by including Lagrangian mechanics and Lagrangian field theory, and even seems redundant.

All the Lagrangian mechanics content (formalism, equations, examples, history, etc.) could be split off to Lagrangian mechanics, and all the field theory content (formalism, equations, examples, history, etc.) split off to another article Lagrangian field theory (which currently redirects to this page Lagrangian).

Then "Lagrangian" could be redirected to the Lagrangian (disambiguation) page with the latter including links to the new Lagrangian mechanics and Lagrangian field theory articles (which makes sense, since in the literature "Lagrangian density" is usually referred to as a "Lagrangian" anyway). Obviously, the relation between the two can be mentioned and both articles can link to each other.

By contrast, this is already the case for Hamiltonian mechanics, Hamiltonian field theory, and "Hamiltonian" is correctly a disambiguation page. Thoughts? M∧Ŝc²ħε И_τlk 21:33, 31 July 2015 (UTC)[reply]

Given the lack of input I'll go ahead and begin splitting off the field theory content to Lagrangian field theory, and the mechanical examples to Lagrangian mechanics. This page will not be a DAB yet (I'll fix the links first before converting into a DAB page). M∧Ŝc²ħε И_τlk 09:28, 5 August 2015 (UTC)[reply]

Looks like a good initiative. There are other possible subdivisions to perhaps consider later. YohanN7 (talk) 11:06, 5 August 2015 (UTC)[reply]

Thanks, very almost done with this page, just need to redirect the incoming links to here either to Lagrangian mechanics or Lagrangian field theory, then this article will be redirected to the DAB page. M∧Ŝc²ħε И_τlk 11:52, 5 August 2015 (UTC)[reply]

Done.... finally. Hundreds of pages have been disambiguated by removing links to "Lagrangian". Now anyone who links to here will realize they have to find the correct topic named after Lagrange. M∧Ŝc²ħε И_τlk 23:00, 5 August 2015 (UTC)[reply]

The one thing that is called a Lagrangian (as opposed to "Lagrangian something" where Lagrangian is an adjective) should be first in the list.--92.208.33.124 (talk) 07:40, 8 January 2017 (UTC)[reply]

Transfer of content from this article (Lagrangian) to Lagrangian mechanics and Lagrangian (field theory)[edit]

I transferred the examples and some content from this article (Lagrangian) to the Lagrangian mechanics and Lagrangian (field theory) articles. M∧Ŝc²ħε И_τlk 09:55, 5 August 2015 (UTC)[reply]

Summary of main content transfers[edit]

So don't claim I stole anyone's work because the credit is given in these links. M∧Ŝc²ħε И_τlk 11:26, 5 August 2015 (UTC)[reply]

Contested deletion 1[edit]

This page should not be speedily deleted because... the term is not ambiguous. All of these subjects stem from the studies fo the same individual. And that surnams has become a mainstay in our contemporary language!! — Preceding unsigned comment added by 2602:304:6E1A:3529:C80E:25DD:EB82:FFD0 (talk) 21:42, 10 September 2015 (UTC)[reply]

Also, what would be done to preserve the editing history which is lengthy and complex? It must be kept to comply with copyright laws and for other reasons. JRSpriggs (talk) 03:25, 11 September 2015 (UTC)[reply]

Contested deletion 2[edit]

This page should not be speedily deleted because this has to be requested through WP:RM with a request to merge page histories. This page has a long history of contributions which has to be preserved for attribution under GFDL. --Δρ.Κ. ^{λόγοςπράξις} 04:35, 11 September 2015 (UTC)[reply]

Contested deletion 3[edit]

This page should not be speedily deleted because... (your reason here) --213.160.181.108 (talk) 10:25, 11 September 2015 (UTC)[reply]

That's a start. Now your actual justifiable reason?? M∧Ŝc²ħε И_τlk 11:16, 11 September 2015 (UTC)[reply]

CSD withdrawn[edit]

Misplaced per MOS:DABPAGENAME. Widefox; talk 15:04, 11 September 2015 (UTC)[reply]

Done I boldly cut/paste moved the dab (see my comment about copyright). Hopefully we won't either have a non-functioning redirect or misplaced dab hanging around now. Widefox; talk 15:22, 11 September 2015 (UTC)[reply]
