On inductive limits of matrix algebras of holomorphic functions

Abstract

Let A \mathfrak {A} be a UHF algebra and A ( D ) \mathcal {A}({\mathbf {D}}) the disk algebra. If A = [ ∪ n ≥ 1 A n ] − \mathfrak {A} = {\left [ {{ \cup _{n \geq 1}}{\mathfrak {A}_n}} \right ]^ - } and α \alpha is a product-type automorphism of A \mathfrak {A} which leaves each A n {\mathfrak {A}_n} invariant, then α \alpha defines an embedding \[ A n ⊗ A ( D ) ↪ ı n A n + 1 ⊗ A ( D ) \mathfrak {A}_n \otimes \mathcal {A}({\mathbf {D}}) \stackrel {\imath _n}{\hookrightarrow } {\mathfrak {A}_{n + 1}} \otimes \mathcal {A}({\mathbf {D}}) \] . The inductive limit of this system is a Banach algebra whose maximal ideal space is closely related to that of the disk algebra if the Connes spectrum Γ ( α ) \Gamma (\alpha ) is finite.
