Closure
Summary
The closure of a subset of a topological space is the intersection of all closed sets that contain it. It is the smallest closed set that contains the subset. In a metric space, it is the set of limits of convergent sequences of points of the subset.
What this node needs for W2
- edge instance_of in: at least two examples (0 of 2)
- edge not_instance_of in: at least one non-example (0 of 1)
- edge specializes both: the more general notions and the special cases (0 of 1)
The writing levels say how complete the text of a node is. They do not measure its truth.
