Double origin topology

http://dbpedia.org/resource/Double_origin_topology an entity of type: Thing

In mathematics, more specifically general topology, the double origin topology is an example of a topology given to the plane R2 with an extra point, say 0*, added. In this case, the double origin topology gives a topology on the set X = R2 ∐ {0*}, where ∐ denotes the disjoint union. rdf:langString
