  Isomorphism   (Site not responding. Last check: 2007-11-06)
The word "isomorphism" applies when two complex structures can be mapped onto each other, in such a way that to each part of one structure there is a corresponding part in the other structure, where "corresponding" means that the two parts play similar roles in their respective structures.
Isomorphic structures are "the same" at some level of abstraction; ignoring the specific identities of the elements in the underlying sets, and focusing just on the structures themselves, the two structures are identical.
In sociology, isomorphism is to a kind of "copying" or "imitation", especially of the practices of one organization by another.

However, there are circumstances in which the isomorphism class of an object conceals vital internal information about it; for example, in
conjugate subgroups, and therefore amalgamating the elements of an isomorphism class into a single featureless object seriously decreases the level of detail provided by the theory.
