An isomorphism from a structure to itself is known as an automorphism. As a result, isomorphic structures can be recognized and cannot be discriminated solely based on their structure.

An isomorphism in mathematics is a structure-preserving mapping that allows for the reversal of two structures of the same kind. If there is an isomorphism between any two mathematical structures, they are said to be isomorphic. The Greek words isos, which means "equal," and morphe, which means "form" or "shape," are the roots of the word "isomorphism."

Because two identical objects areomorphic, there is interest in them due to their shared characteristics (excluding further information such as additional structure or names of objects). As a result, isomorphic structures can be recognized and cannot be discriminated solely based on their structure. According to mathematical language, two objects are equal up to an isomorphism.
