norm {vector}. The norm must be {homogeneous} and {symmetric} and fulfil the following condition: the shortest way to reach a point is to go straight toward it. Every {convex} symmetric {closed} surface surrounding point 0 introduces a norm by means of {Minkowski functional}; all vectors that end on the surface have the same norm then. The most popular norm is the {Euclidean norm}; it is calculated by summing up squares of all coordinates and taking the square root; this is the essence of {Pythagorus's theorem}. In the infinite-dimensional case, the sum is infinite or is replaced with an integral when the number of dimensions is {uncountable}. (1998-07-05) |
