Keyboard graph navigation: press N for concepts or E for relations; use arrow keys, Home, and End to move; Enter selects; Shift plus Enter selects and centers; plus and minus zoom; zero fits; Escape clears the selection. Use the visible viewport buttons as alternatives to dragging, wheel, and pinch gestures.
Select a concept
Select any concept, construction junction, or annotated relation by pointer, touch, search, or keyboard.
Construction junctions are diamonds. They show where multiple structures must coexist on the same carrier and satisfy compatibility conditions.
Move selected concept
Single-pointer and keyboard alternatives to dragging. Each activation moves the selected concept one step.
This is an authored directed relation from the source endpoint to the target endpoint.

satisfies primality
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.

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.
