Blaschke C* -algebras

open access: yes, 2020
© 2020, PleiadesT Publishing,T Ltd. Abstract: In the paper we introduce the notion of the Blaschke C*-algebra and we consider the isometric representations of uniform Blaschke algebra. We extend the Coburn’s Theorem for a family of non-unitary isometries

Schauder Basis with Finite Blaschke Products

open access: yes
We construct a Schauder basis for the space $Hol(\mathbb D)$, the space of holomorphic functions on the closed unit disk, consisting entirely of finite Blaschke products. The expansion coefficients are given explicitly. Our result remains valid when $Hol(\mathbb D)$ is equipped with a broader class of norms satisfying natural structural conditions ...

Algebras associated with blaschke products of type g

open access: yes, 2003
Let Ω (resp. Ωfi) be the set of all interpolating Blaschke products of (resp. finite) type G. Let E (resp. Efi) be the Douglas algebra generated by H∝ and the complex conjugates of elements of Ω (resp. Ωfi).

Classification of some finite Blaschke products as metric endomorphisms

open access: yes, 1986
It is shown that for n = 1, 2, 3,…, 0 ⩽ t < 1, the Blaschke product zn(z − t)(1 − zt) restricted to the unit circle has Lebesgue measure theoretic entropy given by h = log12{(n + 1) + (n − 1) t2 + [(n + 1)2 − 2(n2 + 1) t2 + (n − 1)2 t4]12}.
