Location (topology)

Topologies describe mathematical properties. Such properties may be represented with graphs or meshes of vertices or nodes and edges. The adjacence of vertices to each other are qualified as neighbourhoods. The distance between vertices along edges is measured in hops from one vertex to the next.

Thus the locations of the vertices are ot determined in coordinates, neither absolute nor relative, but in connecting edges and adjacent vertices. Respectively the locations of edges are equally not determined in coordinates, but in originating or terminating vertices.

Such edges may be originated in the vertices or terminated in the vertices. The edges may be directed or not directed. The starting vertex end the terminating vertex may be identical.
