Definition:Strongly Positive Quadratic Functional

Definition
Let $ J \left [ y \right ]$ be a quadratic functional, defined on some normed linear space.

Let there be $ k$ such that


 * $ \forall k \in \R_{ > 0} : J \left [ y \right ] \ge k \left \vert h \right \vert^2$

Then the quadratic functional $ J $ is called strongly positive.
