Representations of Logmodular Algebras
February 29, 3pm; PGH 646
Abstract
It has been known since the 1950's that every contractive
representation
of the disk algebra is completely contractive. Surprisingly, for just
about as
long it has been an open problem to decide whether or not every
contractive
representation of the algebra of bounded analytic functions on the disk is
completely contractive. An analogous problem of Davidson asks whether or
not every contractive representation of a nest algebra is completely
contractive. These algebras are examples of logmodular algebras.
We will present new proofs of some of the known results on these problems
together with an operator space proof of a key result in Banach space
theory.
This talk is based on joint work with Mrinal Raghupathi.
