Talk:Mathisson–Papapetrou equations

Merge?
Should we merge
 * Papapetrou–Dixon equations
 * Mathisson–Papapetrou equations
 * Mathisson–Papapetrou–Dixon equations

into one big article? They seem so similar. It seems the more common names are "Mathisson–Papapetrou" and "Mathisson–Papapetrou–Dixon", much more than "Papapetrou–Dixon". M&and;Ŝc2ħεИτlk 14:07, 27 October 2013 (UTC)
 * That sounds like a good idea. Should it all be merged to Mathisson–Papapetrou–Dixon equations then? static shakedown ʕ •ᴥ•ʔ 14:24, 27 October 2013 (UTC)


 * That's what I was thinking. Let's ask Wikipedia talk:WikiProject Physics. M&and;Ŝc2ħεИτlk 14:33, 27 October 2013 (UTC)


 * Trivial matter, so it's done. M&and;Ŝc2ħεИτlk 17:40, 27 October 2013 (UTC)


 * Support Merger is a good idea. The two referenced articles are very similar and the unreferenced one is similar. The best article title is probably best decided based on the most common usage in the literature. For GScholar, "Mathisson–Papapetrou–Dixon equations" gets 29 hits, "Papapetrou–Dixon equations" gets 43 hits (of which some have the Mathisson prepended) and "Mathisson–Papapetrou equations" gets 118 hits. "Mathisson–Papapetrou equations" gets 83 hits in GBooks, "Mathisson–Papapetrou–Dixon equations" gets 1 hit in GBooks, and "Papapetrou–Dixon equations" gets 8 hits. So ti looks like "Mathisson–Papapetrou equations" is the most common usage, at least as far as Google is concerned. The other alternative names should be mentioned in the lead, too. --Mark viking (talk) 17:42, 27 October 2013 (UTC)


 * Sorry, I missed this comment just now.
 * It seems the MPD equations are more general, while the MP equations are a special case, with various constraints for each equation. I can't seem to find the PD equations (when I look all that keeps coming up on google, google books and scholar are the MPD equations). Consequently keeping the title "MPD equations" seems the best for now.
 * Thanks for your input, as always. M&and;Ŝc2ħεИτlk 17:51, 27 October 2013 (UTC)
