A vector space V over a field F is a set equipped with a binary operation +:V×V→V and function F×V→V called vector addition and scalar multiplication, respectively, satisfying the following axioms (self-evident "ground rules" that require no justification) for all vectors u→,v→,w→...

Space Vector In subject area: Engineering A vector space is a set having a commutative group addition, and a multiplication by another set of quantities (magnitudes) called a field. From: Encyclopedia of Physical Science and Technology (Third Edition), 2003 About this pageSet alert Discover ...
In this chapter, we take a closer look at a finite field extension F < E from the point of view that E is a vector space over F. It is clear, for instance, that any σ ∈ G F (E) is a linear operator on E over F. However, there are many linear operators that are not ...
A non empty set {eq}V {/eq} is said to form vector space over a field {eq}F {/eq} if it satisfies the following properties. (i) There is a binary... Learn more about this topic: Vector Space Definition, Axioms & Examples

In the field of natural language processing, converting text data to numerical form is known as vectorization. The vectors of a set of documents in a common vector space is referred as vector space model (Manning et al., 2008). Since the model is based on linear algebra, it allows vector...
There are a number of additional properties that vector spaces satisfy. However these are not included in the list of axioms because they are consequences of them. Theorem 2: If V is a vector space over the field F then for all u, v ∈ V and all λ, µ ∈ F: (1) 0v = ...
What is a Vector Field? Vector Fields:Vector fields are a way of visually representing equations that govern forces or other directional quantities as their properties change over a given space. The vectors within a given field represent how an object placed in the field will behave at any give...
