Book
An introduction to Hilbert space
TL;DR: In this paper, the authors present an introduction to the theory of Hilbert space and its applications, particularly to the solution of partial differential equations in mathematical physics and to the approximation of functions in complex analysis.
Journal ArticleDOI
A Commutant Lifting Theorem for a Domain in C2and Spectral Interpolation
Jim Agler,Nicholas Young +1 more
TL;DR: In this paper, a necessary condition for the existence of an analytic 2×2 matrix function satisfying interpolation conditions and bounds on eigenvalues was obtained for the spectral Nevanlinna-Pick problem.
Journal Article
A model theory for Γ-contractions
Jim Agler,Nicholas Young +1 more
TL;DR: In this article, the authors show that any Γ-constraint is unitarily equivalent to the restriction to a joint invariant subspace of the orthogonal direct sum of a Γunitary and a model Γ contraction of the form (Tψ, Tz) where Tψ and Tz are suitable blockToeplitz operators on a vectorial Hardy space.
Journal ArticleDOI
A Schwarz Lemma for a domain related to μ-synthesis
TL;DR: In this article, a special case of the μ-synthesis problem is applied to a special class of automorphisms, and the authors prove a Schwarz lemma for a domain that arises in connection with control theory.
