A characterization of local-global \(f\)-rings. (English) Zbl 0792.06019

Martinez, J. (ed.) et al., Ordered algebraic structures. The 1991 Conrad conference, held at the University of Florida, Gainesville, USA, December 12-14, 1991, dedicated to Paul F. Conrad on the occasion of his 70th birthday. Dordrecht: Kluwer Academic Publishers. 235-249 (1993).
Summary: We look at the interplay between algebraic properties of commutative semi-prime \(f\)-rings vis-a-vis topological properties of the maximal spectra of these rings. We are able to show that, in the case of a strong unit, an \(f\)-ring has the local-global property precisely when its maximal spectrum is zero-dimensional. We also obtain a first-order characterization of this occurrence. We then consider under what conditions we can omit the assumption of a strong unit. These results are then translated to the case where the ring under consideration is \(C(X)\), the ring of continuous real valued functions.
