Pronunciation of `Rng` - the non-unital Ring
I chuckled the first time I heard that a Ring
without a multiplicative identity (Ring without the i
) is called a Rng
(pronounced wrong). According to Wikipedia, it's pronounced rung.
How is Rng
pronounced in research/academia?
I've always heard it said "rung" since that is close to a phonetic attempt.
But really, in most serious stuff, I think it's preferred to say "in this paper, rings are not assumed to have identity."
You might also enjoy knowing that there is a similar thing done for semirings, that is, a structure like a ring, but the requirement for additive inverses is omitted. Some people call them rigs since they are missing negatives.
