The State of Subnormal Operators

  • Chapter
Book cover A Glimpse at Hilbert Space Operators

Part of the book series: Operator Theory Advances and Applications ((OT,volume 207))

Abstract

In this paper we present the highlights of the theory of subnormal operators that was initiated by Paul Halmos in 1950. This culminates in Thomson’s Theorem on bounded point evaluations where several applications are presented. Throughout the paper are some open problems.
