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. WebThe norm of a vector is sometimes denoted jvj rather than kvk. Norms are de ned for Rn as well kvk = k(v 1;v 2;:::;v n)k = q v2 1 + v2 2 + + v2 n = v u u t Xn k=1 v2 k: In many ways, norms act like absolute values. For instance, the norm of any vector is nonnegative, and the only vector with norm 0 is the 0 vector. Like absolute values, norms ... howard gsk fellowship
