Summary

A proper ideal PP of a commutative ring such that ab∈Pab\in P implies a∈Pa\in P or b∈Pb\in P; equivalently, the quotient R/PR/P is an integral domain.

Permalink to relation

This is an authored directed relation from the source endpoint to the target endpoint.

Authored explanation

Prime ideals are the proper ideals for which a product can enter the ideal only through at least one factor, a condition equivalent in commutative rings to domain-valued quotient.

How to interpret this relation type

The target is a member or subtype of the broader source class.

Permalink to relation

This is an authored directed relation from the source endpoint to the target endpoint.

Authored explanation

The prime spectrum of a commutative ring is formed from its prime ideals, equipped with the Zariski topology and its canonical structure sheaf.

How to interpret this relation type

Apply a standard functorial or canonical construction whose output is not merely a reduct of the input and is not generally an equivalent presentation of the same object.
