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.
The algebra whose elements are congruence classes of an algebra and whose basic operations are induced on those classes by compatibility of the congruence.
This is an authored directed relation from the source endpoint to the target endpoint.

Authored explanation
Congruence compatibility is precisely what makes the value of every induced operation independent of the selected representatives of its input classes.
How to interpret this relation type
A mathematical concept supplies part of the formal language, state space, representation, or analytic machinery used by a scientific or mathematical-physics concept. The source is the mathematical predecessor; this does not claim that physical content follows from mathematics alone.

quotient by a congruence
Authored explanation
Given an algebra A and a congruence θ, identify a and b exactly when aθb; each basic operation is then defined on the resulting θ-classes.
How to interpret this relation type
Identify elements by a stated equivalence relation and equip the quotient with the induced structure. The edge detail must state the representatives and equivalence relation.
