Often while writing papers I find the need to cite particular equations from other papers. For example, the landmark paper by Einstein, Newton, and White (2015) lays out the theory of everything in the equation immutably numbered 42. In some other paper I'd like to cite this equation by number, using exactly the same formatting that would be applied to \eqref
from amsmath
, whatever that may be. Essentially, I want to be able to say something like
One can see that \eqref{eq:my_above_equation} above is a specific case of
\pseudoeqref{42} from \citet{ENW2015}.
The two equation numbers should be typeset identically. I could just hard-code in the (admittedly simple) formatting, but this seems against the spirit of LaTeX, with the same formatting being done both automatically and manually in different places. It also occurred to me to create a ghost equation somewhere at the end of the document, manually set its number, and give it a normal \label{}
, but this idea seems wrong on many levels.
Is there a simple solution for matching the format of eqref
but with hard-coded equation numbers?
