Primes¶
- Identity Element
- The same object routinely plays the role under one operation and a quite different role under another: 0 is neutral for addition and absorbing for multiplication, and the empty set is neutral for union and absorbing for intersection.
This sourceCovers both the ring case, where 0 is neutral for addition and annihilating for multiplication, and lattices, where each universal bound is neutral for one operation and absorbing for the other, so the role attaches to an element-and-operation pair.

Verification¶
Does it exist? Not checked yet. This entry carries no identifier to resolve. It was extracted from the citation as written in the article, normalized, and deduplicated against the rest of the registry.
Does it back the claim? Not recorded. Neither this nor any other of the 2 citations of this work carries a recorded support check.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
