Analytic Approximation of Matrix Functions

  • Vladimir Peller
Part of the Springer Monographs in Mathematics book series (SMM)


We study in this chapter the problem of approximating an essentially bounded matrix function on 𝕋 by bounded analytic matrix functions in D. For such a matrix function Φ. ∈ L(𝕄 m,n ) its L norm ||Φ||L is, by definition,
$$ {\left\| \Phi \right\|_{{L\infty }}} = ess\mathop{{\sup }}\limits_{{\zeta \in T}} {\left\| {\Phi \left( \zeta \right)} \right\|_{{{M_{{m,n}}}}}} $$
