In mathematics, in reference to an arbitrary element (e.g., a human, an object, a computer), within a well-defined set (called the "anonymity set"), "anonymity" of that element refers to the property of that element of not being identifiable within this set. If it is not identifiable, then the element is said to be "anonymous".

A pseudonym (/ ˈ sj uː d ə n ɪ m /; from Ancient Greek ψευδώνυμος (pseudṓnumos) 'lit. falsely named') or alias (/ ˈ eɪ l i. ə s /) is a fictitious name that a person assumes for a particular purpose, which differs from their original or true meaning ().
Identity (mathematics), an equality that holds regardless of the values of its variables; Identity element, an element of the set which leaves unchanged every element when the operation is applied; Identity function, a function that leaves its argument unchanged; Identity matrix, with ones on the main diagonal, zeros elsewhere
An identity is an equation that is true for all possible values of the variable(s) it contains. Many identities are known in algebra and calculus. In the process of solving an equation, an identity is often used to simplify an equation, making it more easily solvable. In algebra, an example of an identity is the difference of two squares:
Nomen nescio (pronounced [ˈnoːmɛn ˈnɛskɪ.oː]), abbreviated to N.N., is used to signify an anonymous or unnamed person. From Latin nomen – "name", and nescio – "I do not know", it literally means "I do not know the name". [1]
Identity is the set of qualities, beliefs, personality traits, appearance, or expressions that characterize a person or a group. [1] [2] [3] [4]Identity emerges during childhood as children start to comprehend their self-concept, and it remains a consistent aspect throughout different stages of life.
In fact, every element can be a left identity. In a similar manner, there can be several right identities. But if there is both a right identity and a left identity, then they must be equal, resulting in a single two-sided identity. To see this, note that if l is a left identity and r is a right identity, then l = l ∗ r = r.
