Abstract

Given Hilbert space operators A, B, C, one seeks an operator D such that $\| \left( \begin{array}{cc} A ~ C\\ B ~ D\end{array} \right) \| \leqq \mu$ for a pre-assigned bound $\mu$. In some contexts only the existence of D is called for; in others, one may want to know something about those D which work. This paper gives an exposition of the main theorems and of two of the many applications.
