... Each row represents the exponent vector of one of the n2-1 numbers starting with n=2 and going through n=11. Thus the 8th row in the matrix represents the number 80=24∙51. With an appropriate selection of different numbers n2-1 one can form exponent vectors consisting of all even elements and hence ...

We then denote by F(x) the set of all fractions of elements of F[x] (just don’t divide by zero). Our field of rational functions from ...

Basis (linear algebra)
Basis vector redirects here. For basis vector in the context of crystals, see crystal structure. For a more general concept in physics, see frame of reference.A set of vectors in a vector space V is called a basis, or a set of basis vectors, if the vectors are linearly independent and every vector in the vector space is a linear combination of this set. In more general terms, a basis is a linearly independent spanning set.Given a basis of a vector space V, every element of V can be expressed uniquely as a linear combination of basis vectors, whose coefficients are referred to as vector coordinates or components. A vector space can have several distinct sets of basis vectors; however each such set has the same number of elements, with this number being the dimension of the vector space.
