different between isomorphism vs automorphism
isomorphism
English
Etymology
iso- +? -morphism
Pronunciation
Noun
isomorphism (plural isomorphisms)
- Similarity of form

- The postulated isomorphism between words and things constitutes the characterizing feature of all philosophically based universal languages.
- (biology) the similarity in form of organisms, which may be due to convergent evolution or shared genetic background, e.g. an algae species in which the haploid and diploid life stages are indistinguishable based on morphology.
- (chemistry) the similarity in the crystal structures of similar chemical compounds
- 1874 C. Rammelsberg, "Crystallographic and chemical relations of the natural sulphides, arsenides, and sulpharsenides", The Chemical News and Journal of Physical Science, page 197.
- The isomorphism of compounds does not prove the isomorphism of their respective constituents.
- 1874 C. Rammelsberg, "Crystallographic and chemical relations of the natural sulphides, arsenides, and sulpharsenides", The Chemical News and Journal of Physical Science, page 197.
- (sociology) the similarity in the structure or processes of different organizations

- A one-to-one correspondence
- (group algebra) A bijection f such that both f and its inverse f ?1 are homomorphisms, that is, structure-preserving mappings.
- (computer science) a one-to-one correspondence between all the elements of two sets, e.g. the instances of two classes, or the records in two datasets
- (category theory) A morphism which has an inverse; the composition of the morphism and its inverse yields either one of two identity morphisms (depending on the order of composition).

automorphism
English
Etymology
auto- +? morphism
Noun
automorphism (plural automorphisms)
- (algebra) An isomorphism of a mathematical object or system of objects onto itself.
- The ascription to others of one's own characteristics.
Usage notes
- (algebra):
- An automorphism is characterised by the structure it preserves, which is usually specified as an object type. Thus one may speak of a group automorphism or ring automorphism.
- The identity mapping is sometimes called the trivial automorphism; any other automorphism may then be called a nontrivial automorphism.
Synonyms
- (isomorphism of a mathematical object or system of objects onto itself): self-map
- (ascription to others of one's own characteristics): projection
Hypernyms
- (algebra): isomorphism, endomorphism
Hyponyms
