• Mathematical spaces
  • Vector spaces
    • a vector space (also called a linear space) is a set whose elements, often called vectors, may be added together and multiplied (scaled) by numbers called scalars.
  • real coordinate space
    • In mathematics, the real coordinate space or real coordinate n-space, of dimension n
  • Euclidean space
  • Topological space

In mathematics, a space is a set (sometimes known as a universe) with a definition (structure) of relationships among the elements of the set. While modern mathematics uses many types of spaces, such as Euclidean spaces, linear spaces, topological spaces, Hilbert spaces, or probability spaces, it does not define the notion of space itself.
