The setting up of equivalences between points on a map or, on occasion, between points on more than one map. These points are usually otherwise unconnected, although there are interesting looping possibilities otherwise.

There are many mechanisms for specifying mappings:

Note that mapping is distinct from tunnelling, although the results achieved may superficially be similar.

The following are some key differentiators between mapping and tunnelling:

  1. Tunnelling is selective at point of transfer, whereas mapping is indiscriminate upon application of the map.
  2. Mapping folds the manifold to force all mapped elements to the same point, whereas tunnelling forms a temporary conduit.
  3. Movement between mapped points is instantaneous because the points are considered coexistent, while tunnel traversal has a measurable travel time.
