I am looking for a shorthand (or a symbol) for "we have" or its equivalent variants that is not too uncommon. In general I am looking for a notation (shorthand or a symbol) that signals the reader that what follows this sign are quoted facts rather than assumptions or consequents. Just want to increase the efficiency when it comes to hand-written mathematics.
I originally tended to use the shorthand "N.t." for "note that" to fulfill that purpose. However, I learned it is risky in that people not very mathematically minded tend to find it condescending or whatever that compromises the point. So any suggestion that satisfies the desired purpose, even if it is not a shorthand for "we have" (probably a better one), is equally welcomed. Thanks a lot.
