Zermelo–Fraenkel set theory
Axiomatic system that was proposed in the early twentieth century in order to formulate a theory of sets free of paradoxes such as Russell's paradox.
Subsets are commonly constructed using set builder notation.
List comprehension
Syntactic construct available in some programming languages for creating a list based on existing lists.
It follows the form of the mathematical set-builder notation (set comprehension) as distinct from the use of map and filter functions.
Primitive notion
Concept that is not defined in terms of previously-defined concepts.
To establish sets he also requires propositional functions as primitive, as well as the phrase "such that" as used in set builder notation.

Willard Van Orman Quine
American philosopher and logician in the analytic tradition, recognized as "one of the most influential philosophers of the twentieth century".
He was delighted to discover early in his career that all of first order logic and set theory could be grounded in a mere two primitive notions: abstraction and inclusion.
Type theory
Formal system in which every "term" has a "type".
Set theory has set-builder notation. It can create any set that can be defined. This allows it to create Uncountable sets. Type theories are syntactic, which limits them to a countably infinite terms. Additionally, most type theories require computation to always halt and limit themselves to recursively generable terms. As a result, most type theories do not use the Real numbers but the Computable numbers.
Big O notation
Mathematical notation that describes the limiting behavior of a function when the argument tends towards a particular value or infinity.
For these reasons, it would be more precise to use set notation and write f(x) ∈ O(g(x)) (read as: "f(x) is an element of O(g(x))", or "f(x) is in the set O(g(x))"), thinking of O(g(x)) as the class of all functions h(x) such that |h(x)| ≤ C|g(x)| for some constant C.
Interval (mathematics)
Set of real numbers that contains all real numbers lying between any two numbers of the set.
Thus, in set builder notation,
Colon (punctuation)
Punctuation mark consisting of two equally sized dots placed on the same vertical line.
In mathematical logic, when using set-builder notation for describing the characterizing property of a set, it is used as an alternative to a vertical bar (which is the ISO 31-11 standard), to mean "such that".
