Closure meaning math
In geometry, topology, and related branches of mathematics, a closed set is a set whose complement is an open set. In a topological space, a closed set can be defined as a set which contains all its limit points. In a complete metric space, a closed set is a set which is closed under the limit operation. This should not be confused with a closed manifold. WebClosure is an idea from Sets. It is when an operation (such as "adding") on members of a set (such as "real numbers") always makes a member of the same set. Closure
