ノルム線型空間
1. Normed vector spaceIn mathematics, with 2- or 3-dimensional vectors with real-valued entries, the idea of the "length" of a vector is intuitive and can easily be extended to any real vector space R. The following properties of "vector length" are crucial. 1. The zero vector, 0, has zero length; every other vector has a positive length. if 2. Multiplying a vector by a positive number changes its length without changing its direction. Moreover, for any scalar 3. The triangle inequality holds.
