A **positive linear operator** is a type of linear transformation that maps elements from one vector space to another while preserving certain order properties. More formally, let \\( V \\) and \\( W \\) be vector spaces over the same field (usually the field of real numbers \\(\\mathbb\{R\}\\) or complex numbers \\(\\mathbb\{C\}\\)).
