From The Free On-line Dictionary of Computing (13 Mar 01) [foldoc]:
norm
A real-valued function modelling the length of a
{vector}. The norm must be {homogeneous} and {symmetric} and
fulfil the following condition: the shortest way to reach a
point is to go straight towards 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}.
