- Biol. a similarity in appearance or structure of organisms belonging to different species or races
- Chem. an identity or close similarity in the crystalline form of substances usually containing different elements but having similar composition
- Math. a one-to-one correspondence between two mathematical systems, sets, etc. that preserves the basic operations, as the correspondence between binary numbers and decimal numbers, each a set of real numbers
Origin of isomorphismfrom isomorphic + -ism
- Biology Similarity in form, as in organisms of different ancestry.
- Mathematics A one-to-one correspondence between the elements of two sets such that the result of an operation on elements of one set corresponds to the result of the analogous operation on their images in the other set.
- A close similarity in the crystalline structure of two or more substances of similar chemical composition.
- Similarity of form
- 2. 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).
