Preparing the interactive atlas…
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.
No alternate terminology is currently authored for this record.
Carrier(s)
dcpo P
Data
least element ⊥
Axioms / constraints
⊥≤x for every x
Notes
Terminology varies: some authors use CPO for a dcpo without requiring a least element; this atlas uses “pointed CPO”. The least element is unique if it exists.
