vector space
Definition from Dictionary, a free dictionary
There's night and day, brother, both sweet things; sun, moon, and stars, brother, all sweet things; there's likewise a wind on the heath. Life is very sweet, brother; who would wish to die?
George BorrowEnglish
Noun
Wikipedia- (mathematics) A type of set of vectors that satisfies a specific group of constraints.
- A vector space is a set of vectors which can be linearly combined.
vector space over the field F
- (linear algebra) A set V, whose elements are called "vectors", together with a binary operation + forming a module (V,+), and a set F^{*} of bilinear unary functions f^{*}:V→V, each of which corresponds to a "scalar" element f of a field F, such that the composition of elements of F^{*} corresponds isomorphically to multiplication of elements of F, and such that for any vector v, 1^{*}(v) = v.
- Any field <math>\mathbb{F}</math> is a one-dimensional vector space over itself.
- If <math>\mathbb{V}</math> is a vector space over <math>\mathbb{F}</math> and S is any set, then <math>\mathbb{V}^S=\{f|f:S\rightarrow \mathbb{V} \}</math> is a vector space over <math>\mathbb{F}</math>, and <math> \mbox{dim} ( \mathbb{V}^S ) = \mbox{card}(S) \, \mbox{dim} (\mathbb{V})</math>.
- If <math>\mathbb{V}</math> is a vector space over <math>\mathbb{F}</math> then any closed subset of <math>\mathbb{V}</math> is also a vector space over <math>\mathbb{F}</math>.
- The above three rules suffice to construct all vector spaces.
