Everything about Positive operator
In mathematics, a linear operator acting on inner product space
In mathematics as well as physics, a linear operator acting on an inner product space is called positive-semidefinite if, for every, and, where is the domain of. Positive-semidefinite operators are denoted as. The operator is said to be positive-definite, and written, if for all. Wikipedia →
