Sublinear function
From Wikipedia, the free encyclopedia
A sublinear function, in linear algebra and related areas of mathematics, is a function 
on a vector space V over F, an ordered field (e.g. the real numbers 
), which satisfies, for all scalars γ and vectors x and y
(positive homogenity)
(subadditivity)
[edit] Examples
- Every (semi-)norm is a sublinear function
[edit] Properties
- Every sublinear function is a convex function
