vector space

vector space (plural vector spaces)

1. (algebra, geometry, topology) A set of elements called vectors, together with some field and operations called addition (mapping two vectors to a vector) and scalar multiplication (mapping a vector and an element in the field to a vector), satisfying a list of constraints.

   A vector space is a set of vectors which can be linearly combined.

   Each vector space has a basis and dimension.
