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.

Content version 2.3.0
Alternate terminology No alternate terminology is currently authored for this record. Axioms / constraints Hausdorff T 2 T_{2} T 2 axiom Incoming relations (arrows to this concept) Each relation below ends at this concept.
This is an authored directed relation from the source endpoint to the target endpoint.
Relation ID metric_to_hausdorff
Relation type Theorem implication theorem-implication
Direction source → target
Endpoint roles source: Implies by theorem; target: Follows by theorem from
Authored annotation is Hausdorff Authored explanation Distinct points have disjoint sufficiently small metric balls.
How to interpret this relation type Record a genuine theorem implication that is not part of the target definition; these edges may point toward a weaker structure.
This is an authored directed relation from the source endpoint to the target endpoint.

Direction source → target
Endpoint roles source: Builds toward; target: Built from
Authored annotation + disjoint neighborhoods Authored explanation Require distinct points to have disjoint neighborhoods.
How to interpret this relation type Keep the existing data and select the subclass satisfying an additional law, existence condition, finiteness condition, or other property.
