In mathematics, majorization is a preorder on vectors of real numbers. Let $${\displaystyle {x}_{(i)}^{},\ i=1,\,\ldots ,\,n}$$ denote the $${\displaystyle i}$$-th largest element of the vector $${\displaystyle \mathbf {x} \in \mathbb {R} ^{n}}$$. Given See more (Strong) majorization: $${\displaystyle (1,2,3)\prec (0,3,3)\prec (0,0,6)}$$.
