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