cardinality measure
1Cardinality (disambiguation) — Cardinality may refer to* Cardinality of a set, a measure of the number of elements of a set in mathematics * Cardinality (data modeling), a term in database design * Cardinality (SQL statements), a term used in SQL statements * Cardinal utility …
2Cardinality — In mathematics, the cardinality of a set is a measure of the number of elements of the set . For example, the set A = {1, 2, 3} contains 3 elements, and therefore A has a cardinality of 3. There are two approaches to cardinality ndash; one which… …
3Atom (measure theory) — In mathematics, more precisely in measure theory, an atom is a measurable set which has positive measure and contains no set of smaller but positive measure. A measure which has no atoms is called non atomic or atomless. Contents 1 Definition 2… …
4Counting measure — In mathematics, the counting measure is an intuitive way to put a measure on any set: the size of a subset is taken to be the number of elements in the subset, if the subset is finite, and ∞ if the subset is infinite.[1] Formally, start with a… …
5Constructivism (mathematics) — In the philosophy of mathematics, constructivism asserts that it is necessary to find (or construct ) a mathematical object to prove that it exists. When one assumes that an object does not exist and derives a contradiction from that assumption,… …

7Standard probability space — In probability theory, a standard probability space (called also Lebesgue Rokhlin probability space) is a probability space satisfying certain assumptions introduced by Vladimir Rokhlin in 1940 [1] . He showed that the unit interval endowed with… …

9Lp space — In mathematics, the Lp spaces are function spaces defined using a natural generalization of the p norm for finite dimensional vector spaces. They are sometimes called Lebesgue spaces, named after Henri Lebesgue (Dunford Schwartz 1958, III.3),… …
