Webfor all u;v2V and all 2F. A vector space endowed with a norm is called a normed vector space, or simply a normed space. An important fact about norms is that they induce metrics, giving a notion of convergence in vector spaces. Proposition 1. If a vector space V is equipped with a norm kk: V !R, then d(u;v) , ku vk is a metric on V. Proof.
