- Thus if \mathfrak{D} is an arbitrary decomposition of a space X into mutually disjoint subsets, then the corresponding quotient space is obtained by 'shrinking' or 'identifying' each member of \mathfrak{D} to a single point. For this reason, the quotient spaces are sometimes called identification spaces and quotient maps as
[ sic] identification maps.

- The quotient space obtained from such a relation is called extended Reeb (ER) quotient space. Moreover, the ER quotient space, which is an abstract sub-space of M* and is independent from the geometry, may be represented as a traditional graph, which is called the extended Reeb graph (ERG).
