This article is about a general term. A list of important particular cases (instances) is available at Category:Subspace-hereditary properties of topological spaces


A property of topological spaces is termed hereditary, subspace-hereditary or subspace-closed, if every subset of a topological space having the property also has the property (when the subset is endowed with the subspace topology).
