Definition
Normed Vector Space
Let $\struct {X, \norm \cdot}$ be a normed vector space.
Let $T : X \to X$ be an invertible bounded linear transformation.
We say that $A$ is a bounded linear operator.
Inner Product Space
Let $\struct {X, \innerprod \cdot \cdot}$ be an inner product space.
Let $T : X \to X$ be an invertible bounded linear transformation.
We say that $A$ is a bounded linear operator.
