# What is the borne function mentioned in this paper?

On page 16, first paragraph of this paper, the authors introduce a function called "borne", which divides the normal distribution into n ranges of equal size, without citation. The definition is clear enough for implementation, but I couldn't find any other reference to this function. Where did the authors come up with this name and is there a more standard or more rigorous definition of it somewhere?

It's French for bound or limit (the authors are French) and it means whatever they define it to be ;)

I'm was not aware of this concept before and so I don't know a description or definition in English of the same.
