1. Every ordered basis lives in one equivalence class or another.
2. When the space is zero-dimensional, its ordered basis is empty.
3. After an order is chosen, the basis can be considered an ordered basis.
4. For many purposes it is convenient to work with an "'ordered basis " '.
5. A linear isomorphism is determined by its action on an ordered basis or "'frame " '.
6. It's difficult to find ordered basis in a sentence. 用ordered basis造句挺難的
7. A frame ( or, in more precise terms, a tangent frame ) is an ordered basis of particular tangent space.
8. Since there is no preferred way to choose an ordered basis of a vector space, a frame bundle lacks a canonical choice of identity cross-section.
9. Thus any choice of a privileged ordered basis for " V " determines an orientation : the orientation class of the privileged basis is declared to be positive.
10. Because there is only a single ordered basis \ emptyset, a zero-dimensional vector space is the same as a zero-dimensional vector space with ordered basis.
11. Because there is only a single ordered basis \ emptyset, a zero-dimensional vector space is the same as a zero-dimensional vector space with ordered basis.
12. We then speak of an "'ordered basis "', which we define to be a sequence ( rather than a Ordered bases and coordinates " below.
13. If all zero-dimensional vector spaces are assigned this orientation, then, because all isomorphisms among zero-dimensional vector spaces preserve the ordered basis, they also preserve the orientation.
14. In this setting, the orientation of an ordered basis is a kind of asymmetry that makes a right-handed and left-handed ( or right-chiral and left-chiral ).
15. Note the above isomorphism is canonical : if one is given a module homomorphism between finite-rank free modules, then a choice of an ordered basis corresponds to a choice of an isomorphism F \ simeq R ^ n.
16. Consider the map " f " from " V " to " V " that proceeds by writing a vector in coordinates according to this ordered basis, squaring each of those coordinates, and then finding the vector in " V " that has those new coordinates.
