• Topology [r]: A branch of mathematics that studies the properties of objects that are preserved through continuous deformations (such as stretching, bending and compression). [e]

Other related topics

• 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. [e]
• Boundary [r]: 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. [e]
