In mathematics, a norm is a function from a real or complex vector space to the non-negative real numbers that behaves in certain ways like the distance from the origin: it commutes with scaling, obeys a form of the triangle inequality, and is zero only at the origin. In particular, the Euclidean distance in a Euclidean space is … Ver mais Given a vector space $${\displaystyle X}$$ over a subfield $${\displaystyle F}$$ of the complex numbers $${\displaystyle \mathbb {C} ,}$$ a norm on $${\displaystyle X}$$ is a real-valued function $${\displaystyle p:X\to \mathbb {R} }$$ with … Ver mais For any norm $${\displaystyle p:X\to \mathbb {R} }$$ on a vector space $${\displaystyle X,}$$ the reverse triangle inequality holds: For the $${\displaystyle L^{p}}$$ norms, we have Hölder's inequality Every norm is a Ver mais • Bourbaki, Nicolas (1987) [1981].
