proper cone (Definition)

A proper cone is a cone $ C\subset\mathbb{R}^n$ that satisfies the following:


A proper cone $ C$ induces a partial ordering on $ \mathbb{R}^n$:

$\displaystyle a\preceq b\Leftrightarrow b-a\in C. $
This ordering has many nice properties, such as transitivity, reflexivity, and antisymmetry.
