👉 In mathematics, a deification is a mathematical operation that takes a set of numbers and returns another set of numbers. The operation can be any one-to-one correspondence between two sets (the first set contains the initial input values and the second set contains the output values). For example, in set theory, you might have a deified function from natural numbers to integers, where $f(n) = 2n$ for all natural numbers $n$. This operation is called a deification.
