Compact Operators

Part of the Graduate Texts in Mathematics book series (GTM, volume 225)


If ℌ is a normed linear space, a linear operator T: ℌ → ℌ is called bounded if there exists a constant C such that |Tx| ≤ C|x| for all x ∈ ℌ. In this case, the smallest such C is called the operator norm, of T, and is denoted |T|. The boundedness of the operator T is equivalent to its continuity.
