We show among other things that if B is a Banach function space of continuous real-valued functions vanishing at infinity on a locally compact Hausdorff space X, with the property that for some odd natural number p>1, b 1Γ p # B for all b # B, then B=C 0 (X ).

β¦ Synopsis
The symbolic calculus on Banach algebras of continuous functions and related spaces is studied. In particular, functions operating on the real part of the algebra are considered. The main tool in this paper is an ultraseparation argument. As a consequence it is shown, for example, that (t^{p}) on ([0,1)) for any (p) with (0<p<1) does not operate on the real part of a Banach function algebra on a compact Hausdorff space unless the algebra contains every continuous function. 1993 Academic Press.

## Abstract The presence of a modulus function on a Banach algebra gives rise to tensor product norms analogous to the greatest crossβnorm and allows us to extend the Waelbroeck functional calculus. (Β© 2008 WILEYβVCH Verlag GmbH & Co. KGaA, Weinheim)
Let X be a perfect, compact subset of the complex plane, let (M n ) be a sequence of positive numbers satisfying M 0 =1 and ( m+n n ) M m+n ΓM m M n , and let D(X, M) With pointwise addition and multiplication, D(X, M) is a commutative normed algebra. In this note we study the endomorphisms of such
