Automorphisms of some Banach algebras of analytic functions Original Research Article

In this paper, we factorize an arbitrary automorphism of the algebra considered by Peters in [J. Peters, J. Functional Anal. 59 (1984) 498–534] and its weak version and use it to identify an isomorphism invariant which is the quotient group of the full automorphism group over the maximal ideal fixing automorphisms subgroup.
