内容简介

a classic of pure mathematics, this advanced graduate-level text explores the intersection of functional analysis and analytic func-tion theory. close in spirit to abstract harmonic analysis, it is con-fined to banach spaces of analytic functions in the unit disc.
  the first four chapters examine proofs of classical theorems on boundary values and boundary integral representations of analytic functions in the unit disc, including generalizations to dirichlet algebras. the fifth chapter contains the factorization theory of tip functions, a discussion of some partial extensions of the factoriza-tion, and a brief description of the classical approach to the theorems of the first five chapters. the remainder of the book addresses the structure of various banach spaces and banach algebras of analytic functions in the unit disc...
