  • A Gelfand theory for an arbitrary Banach algebra A is a pair (G;A), such that: A is a C*-algebra and G : A ! A is an algebra homomorphism; G induces a bijection between the set of maximal modular left ideals of A and the set of maximal modular left ideals of A; and for every maximal modular left ideal L of A, the map GL : A=G1(L) ! A=L induced by G has dense range. We prove that if A is a postliminal C*-algebra with Gelfand theory (G;A), then no proper C*-subalgebra of A contains GA. We also show that if J is an ideal of a Banach algebra A such that A=J and J both have Gelfand theories, then A also has a Gelfand theory if we impose some conditions on J and on its Gelfand theory.
