Identity (disambiguation)
See- In mathematics, the term identity, in distinction to an equation, refers to a equational statement that does always hold. Most commonly identities in this sense are used in universal algebra to define a certain class of structures. In another popular usage, an identity is considered as a mathematical entity that does not change other objects. In this spirit, one talks about identity functions, identity elements, identity matices, identity relations, and identity morphisms.
