"Feynman's famous formula"

So what happened with `Feynman's famous formula'? (See Witten et. al., Quantum fields and strings: A course for mathematicians, Volume 1, page 427, Proposition 1.3.) 140.180.10.63 (talk) 08:05, 2 February 2010 (UTC)[reply]

Undefined variable

Can someone define the symbol "alpha" in section "Integrals with differential operators in the argument"? 160.39.34.120 (talk) 05:34, 22 September 2010 (UTC)[reply]

Modified Coulomb potential with mass -- "erroneous correction"?

Over a decade ago, I corrected what appeared to be an error -- a typo, perhaps. Specifically, I changed g(mr) --> 0 to g(mr) --> 1.

I just went over my history of "contributions" and edit differences. It appears that zero is correct after all -- although I could be blundering now instead of ten years ago. It appears to refer to the expression in braces:

$1+{\frac {2}{mr}}+{\frac {2}{(mr^{2})}}\left(e^{mr}-1\right)$

Unless I'm blundering now, that term really does approach zero. It also appears that my "correction" has continued to propagate down to now. Could someone please check this? Wherever I blundered, I sincerely apologize.Johnm307 (talk) 05:04, 6 January 2021 (UTC)[reply]
