1Indexed language — Indexed languages are a class of formal languages discovered by Alfred Aho [ cite journal | last = Aho | first = Alfred | year = 1968 | title = Indexed grammars an extension of context free grammars | journal = Journal of the ACM | volume = 15 |… …
2Indexed family — In mathematics, an indexed family of sets is defined in stages, beginning with the more general concept of an indexed family of elements, which is really just an alternative way of conceptualizing a function or a mapping.First, a mapping f from a …
3Minkowski addition — The red figure is the Minkowski sum of blue and green figures. In geometry, the Minkowski sum (also known as dilation) of two sets A and B in Euclidean space is the result of adding every element of …

5Order topology — In mathematics, an order topology is a certain topology that can be defined on any totally ordered set. It is a natural generalization of the topology of the real numbers to arbitrary totally ordered sets. If X is a totally ordered set, the order …
6Ordinal number — This article is about the mathematical concept. For number words denoting a position in a sequence ( first , second , third , etc.), see Ordinal number (linguistics). Representation of the ordinal numbers up to ωω. Each turn of the spiral… …
7Hilbert space — For the Hilbert space filling curve, see Hilbert curve. Hilbert spaces can be used to study the harmonics of vibrating strings. The mathematical concept of a Hilbert space, named after David Hilbert, generalizes the notion of Euclidean space. It… …
8Dual space — In mathematics, any vector space, V, has a corresponding dual vector space (or just dual space for short) consisting of all linear functionals on V. Dual vector spaces defined on finite dimensional vector spaces can be used for defining tensors… …
9Boolean algebra — This article discusses the subject referred to as Boolean algebra. For the mathematical objects, see Boolean algebra (structure). Boolean algebra, as developed in 1854 by George Boole in his book An Investigation of the Laws of Thought,[1] is a… …
