In this paper, we factorize an arbitrary automorphism of the algebra considered by Peters in [J. Peters, J. Functional Anal. 59 (1984) 498ยฑ534] 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 ยฎxing
Extensive development of noncommutative geometry requires elaboration of the theory of differential Banach \*-algebras, that is, dense \*-subalgebras of C\*-algebras whose properties are analogous to the properties of algebras of differentiable functions. We consider a specific class of such algebra
