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. WebVector Norms and Matrix Norms 4.1 Normed Vector Spaces In order to define how close two vectors or two matrices are, and in order to define the convergence of sequences of vectors or matrices, we can use the notion of a norm. Recall that R + = {x ∈ R x ≥ 0}. Also recall that if z = a + ib ∈ C is a complex number,
