Sun, Shu-Hao Duality on compact prime ringed spaces. (English) Zbl 0821.16045 J. Algebra 169, No. 3, 805-816 (1994). The author studies conditions under which a ring \(R\) is the ring of global sections of some compact ringed space \((X,{\mathfrak F})\) in the sense of C. J. Mulvey [J. Algebra 52, 411-436 (1978; Zbl 0418.18009)]. He introduces the notion of a small weakly Baer ring which generalizes the notion of a Baer ring.The paper contains the following results: 1) A ring \(R\) is isomorphic to the ring of global sections of a compact ringed space \((X, {\mathfrak F})\) for which each stalk of \(\mathfrak F\) is a prime ring if and only if \(R\) is a small weakly Baer ring. 2) The category of small Baer rings is dual to the category of compact prime ringed spaces. 3) The ring of global sections of a ringed space \((X, {\mathfrak F})\) is a Baer ring if and only if \(X\) is a Stone space and each stalk of \(\mathfrak F\) is a domain. 4) The category of Baer rings is dual to the category of compact domain ringed spaces.
