| Dec 30, 2016 at 3:25 | comment | added | Gerhard Paseman | The [] operation reminded me of some similar functions used in the beginnings of tame congruence theory (TCT), and a simple version of this in a monoid context is "undoing" an adjoined unit. One can imagine an iterated version undoing a succession of adjoined units, and this suggested to me operations on congruence classes, which also appears in TCT. Rather than suggest "Find an answer in TCT" (I think you won't), I suggest "Look among congruence preserving polynomial operations", where you might find a name for your relation.
