WebA normed space is a vector space endowed with a norm. The pair (X;kk) is called a normed space. Here are some examples of normed spaces. Example 2.1. Let R be the set of all real numbers. For x2R, set its Euclidean norm jxjto be the absolute value of x. It is easily seen that jxjsatis es N1-N3 above and so it de nes a norm.
