| Jul 20, 2020 at 17:19 | comment | added | Lucas Baldo | I see. Thank you. This normal-ordering is a new concept to me. Since in this case the normal-ordering operatiion is applied to a sum of symbols, I suppose we make use of a linearity of this operation. In other comments of the link you mention I see this linearity property mentioned, but the wikipedia page (en.wikipedia.org/wiki/Normal_order#Notation) afirms: "Attempting to apply normal ordering to a sum of operators is not useful as normal ordering is not a linear operation". Now I'm confused, is normal-ordering a linear operation or not? | |
