For example, for the function () =, the inverse image of {} would be {,}. Again, if there is no risk of confusion, f − 1 [ B ] {\displaystyle f^{-1}[B]} can be denoted by f − 1 ( B ) , {\displaystyle f^{-1}(B),} and f − 1 {\displaystyle f^{-1}} can also be thought of as a function from the power set of Y {\displaystyle Y} to the power set ...

Examples of unexpected applications of mathematical theories can be found in many areas of mathematics. A notable example is the prime factorization of natural numbers that was discovered more than 2,000 years before its common use for secure internet communications through the RSA cryptosystem. [127]
A closed formula, also ground formula or sentence, is a formula in which there are no free occurrences of any variable. If A is a formula of a first-order language in which the variables v 1, …, v n have free occurrences, then A preceded by ∀v 1 ⋯ ∀v n is a universal closure of A.
