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.
