Non-Archimedean Gel'fand theory
1983
Pacific Journal of Mathematics
In this paper we show that if X is a Banach algebra and X Q is its Gelfand subalgebra, then the set Xξ of the elements in X o with compact spectrum is a Gelf and algebra whose maximal ideal space is compact in the Gelίand topology. We also give a representation theorem for Xξ 9 which we use to derive the Van der Put characterization of C-algebras.
