The norm of a function
http://www.personal.psu.edu/~bwo1/courses/Dennis/Chapter11-1.pdf WebJan 8, 2016 · For L 2 ( Ω) (the space of Lebesgue measurable functions on a bounded domain Ω ⊂ R d for which the following norm is finite), the norm of u ∈ L 2 ( Ω) is defined by ‖ u ‖ L 2 2 = ( u, u) L 2 = ∫ Ω u ( x) 2 d x. All this is standard, can be found in any introductory textbook on functional analysis, and is probably already known to you.

WebDifferent functions can be used, and we will see a few examples. These functions can be called norms if they are characterized by the following properties: Norms are non-negative values. If you think of the norms as a length, you can easily see why it can't be negative. Norms are $0$ if and only if the vector is a zero vector. Norms respect the ... 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 … See more 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 1.
