Isomorphism : \I`so*mor"phism\, n. [Cf. F. isomorphisme.]
(Crystallog.)
A similarity of crystalline form between substances of
similar composition, as between the sulphates of barium
({BaSO4) and strontium ({SrSO4}). It is sometimes extended
to include similarity of form between substances of unlike
composition, which is more properly called hom[oe]omorphism.

Isomorphism :
A bijective map between two objects which
preserves, in both directions, any structure under
consideration. Thus a `group isomorphism' preserves group
structure; an order isomorphism (between posets) preserves
the order relation, and so on. Usually it is clear from
context what sort of isomorphism is intended.
