- Closed set [r]: In geometry and topology, a set that contains its boundary; the complement of an open set.
^{[e]} - Topological space [r]: A mathematical structure (generalizing some aspects of Euclidean space) defined by a family of open sets.
^{[e]} - Limit point [r]: A point which cannot be separated from a given subset of a topological space; all neighbourhoods of the points intersect the set.

*Add brief definition or description* - Interior (topology) [r]: The union of all open sets contained within a given subset of a topological space.
^{[e]} - Limit of a sequence [r]: A sequence which converges to (or approaches) the limit a as n tends to infinity.
^{[e]} - Denseness [r]: A set is dense in another set if the closure of the former set equals the latter set.
