Henriksen, Melvin E. Unsolved problems on algebraic aspects of C(X). (English) Zbl 0587.54028 Rings of continuous functions, Pap. Spec. Sess. Annu. Meet. Am. Math. Soc., Cincinnati/Ohio 1982, Lect. Notes Pure Appl. Math. 95, 195-202 (1985). [For the entire collection see Zbl 0559.00006.] The paper is a brief sketch of some old and new problems concerning algebraic and topological aspects of the ring C(X) of all continuous real-valued functions on a Tikhonov space X. We list here a few of them. Problem 1. When is a \(\Phi\)-algebra A isomorphic to C(X) for some (realcompact) X? Problem 3. Is the space of minimal prime ideals P(X) (with the hull-kernel topology) always basically disconnected? Problem 4. Characterize local connectedness of a space X in terms of the ring C(X). The paper contains a comprehensive list of references.
